crease Houdan crests, but result in smallerbirds. The French
crested breeds,Houdans and Crevecoeurs, should havelarge,
well-formed crests that do not inter-fere with the birds
vision.
LaFlecheThe La Fleche take their name from the
town of La Fleche, around which produc-tion was centered in the
early 19th cen-tury. Their actual history goes much far-ther back,
to the 15th century or even ear-lier. Confusion over names given to
localfowl makes it difficult to trace their history,although a more
thorough study could shinesome historical light on that subject.
Theyprobably resulted from crossing Polish,Crevecoeur and Spanish
birds, which gavethem their white ear lobes.
They have sometimes been called theHorned Fowl. Although now
clean-headed,some breeders report occasional offspringwith small
crests or tassels. The Frenchstandard requires a crest. For showing
inthe U.S., select birds with glossy greenishblack feathers and
prominent combs withnicely rounded points. They should havestrong,
well-spaced rangy legs, broadshoulders, full breasts and long,
broadbacks sloping downward from shoulder totail.
Harrison Wier, in his 1905 Poultry Book,didnt understand why the
almostunsurpassable La Fleche were not morepopular in England,
Considering the highexcellence of the breed, in quality,
texture,quantity and flavor of the flesh. He couldntresist taking a
shot at English pretensionsto explain it: One difference
betweenFrench and English people is that theformer understand and
appreciate what isa good table fowl, while the latter only
thinkthey do.
They are recognized only in black, butin the past other colors
were popular. In
Old French BreedsBy Christine Heinrichs
The Old French breeds Houdan,LaFleche and Crevecoeur -- are an
inter-esting group of breeds. This Houdan paint-ing is from Lewis
Wright's Poultry, pub-lished in 1983 by Dr. J. Batty.
All were developed in France as dualpurpose fowl. The La Fleche,
probably theoldest member of the group, was selectedand managed for
egg production in Brit-ain and North America. After the Civil
War,the Houdan became a popular productionbreed with professional
poultry keepers inthe U.S. The breed maintained its statusinto the
early 20th century. While not aspopular, the Crevecoeur was also
used asa production fowl during the same period.Lewis Wright, in
his 1890 Illustrated Bookof Poultry, remarks that they are all
mostdelicious eating.
All three were included in the original1874 APA Standard. They
have long histo-ries, as far as the 15th century in the caseof the
La Fleche, the 17th century for theothers. All are large birds,
topping out at 8lbs. for roosters and 7 lbs. for hens. Allare white
egg layers. All three, in both largefowl and bantam varieties, are
recognizedby the APA for exhibition, and bantams bythe ABA.
HoudansHoudans have been known as
Normandy fowl. Houdans were developedfrom early French market
hybrids. Histori-cally, they were considered one of the besttable
fowl breeds, but are also good egglayers.
All three breeds have V combs. The Vor horn comb, required for
exhibition inthe U.S., is unusual. In England andFrance, the leaf
comb, shaped like butter-fly wings, is still recognized. Leaf
combsare the result of the V comb crossed witha single comb. Dr. J.
Battys Poultry ColourGuide, 1977, shows these drawings of leafand
horn combs. Lewis Wrights IllustratedBook of Poultry, 1890, shows a
prominentleaf comb. Polish, Crevecoeur and Sultanchickens also have
V combs.
Houdans are recognized in the originalmottled black-and-white
and the newer(1914) solid white varieties. Solid black,blue mottled
and red mottled varieties haveexisted in the past and may be raised
byfanciers yet. They have five toes, like theDorkings. Houdan
origins may include bothPolish and Dorkings, popular breeds in
17thcentury France.
Polish are often used as a cross to in-

Poultry Book, notes thatCrevecoeurs are bulkier than the other
twobreeds: Indeed, we have often thought thatit must have had a
cross with the Cochin,which is to some extent borne out by
itsenormous appetite. That difference dis-appeared in the 20th
century. All threebreeds are now the same in weight stan-dard for
large fowl: 8 lbs. for cocks and 6 lbs. for hens. Among bantams,
Houdansare slightly larger, at 34 ounces for cocksand 30 ounces for
hens, compared to 30ounces for La Fleche cocks and 26 ouncesfor
hens, and 30 ounces for Crevecoeurcocks and 27 ounces for
hens.Crevecoeuralso served as a production fowl in the late19th and
early 20th century. They were sopopular that at the Universal
Exhibition inParis in 1855, only two prizes awarded forpoultry: one
for the Crvecoeur and theother for all other breeds of poultry

Sourcing Stock: Part III - Outcrossing
By Brian Reeder
When we seek to outcross, for whateverreason, what we are
actually doing is seekingto bring genes from one individual or
straininto another strain or lineage. At its most ba-sic, that is
all outcrossing is. However, inpractice, it is never really just
that simple,because in addition to the gene or genes wewant to
bring in, we also bring in genes thatwe do not want or that are
neutral to our de-sires, but may have an unforeseen influencelater
on down the line. So while outcrossingcan be an easy enough matter,
there are in-stances where it can be a very complicatedendeavor. In
keeping with the theme of thisseries of articles, we will focus on
bringingin stock to improve a givenlineage of hatchery typebirds,
but the informationpresented herein (and thebasic ideas of
outcrossing)will apply to any outcross-ing project.
So let us say that youhave one or more lines ofbirds of a given
variety ofany given breed that youhave ordered from a hatch-ery and
have been workingto improve, but you feelyou are at an impasse
andmust bring in individuals ofan alternate line to improvea given
trait or traits in yourstock. The first and most important thing
youwill want to consider is whether there are anylines of the breed
or the variety (whetherhatchery or show type) that actually have
thetraits you feel you need to bring in. If the traitsare strictly
visual traits, then likely there willbe a show line that will have
those traits (butnot always). However, if it is some more
in-tangible trait, such as production, resistanceto a given
disease, better fertility or bettertemperament, you might not be
able to findthe desire trait(s) in exhibition lineages of
thevariety of the breed in question and thus youmay need to look
further afield, going out-side of the variety or even the breed you
areworking with. How far you have to go outsideyour variety or
breed will depend on what isactually available, the popularity of
the given
breed or variety and whether you can locateexhibition or
commercial stock that carriesthe trait you need (and then, of
course, whetheryou can actually obtain some stock if you dolocate
such).
The decision to outcross can be a big one,and it can be
traumatic too. If you have a topshow line that is loosing its
fertility, the de-cision to outcross can be very difficult,
be-cause undoubtedly you will not find a linewith high fertility
that has all the bells andwhistles of your top exhibition line.
However,if you have a commercial type strain and de-cide to
outcross to bring in better visual breedtraits, you may actually be
embarking on anexciting journey. While I believe both ex-
amples above are excitingjourneys, I do understandand sympathize
in the caseof the first example.
For the outcross to im-prove phenotype traits,make every effort
to find atleast one young male of thebest line (in terms of
phe-notype traits) that you canfind. Now let me stress thatyou
should make some ef-fort to find a well-ap-pointed show line that
isnot so inbred that it is loos-ing (or has lost) many ofthe
intangible traits such asfertility, egg production(and I DONT mean
com-
mercial level production, just the ability toproduce enough eggs
to derive enough ge-netic diversity to keep the line going)
and/ordisease resistance. I do not mean to belaborthe point about
the intangible traits, but thefrequency with which I mention this
is corre-lated directly to the number of highly diseasesusceptible,
low fertility and/or nearly non-productive show lines I have worked
with andwitnessed over the years. So when looking foran outcross,
always consider these pointsalong with the phenotype traits, as it
is veryeasy to bring very destructive traits into yourcommercial,
hatchery line when making suchoutcrosses. Some of these deleterious
traitsare recessive and may not be obvious in yourline for some
years after the outcross. Bewarned! Not all top lines are actually
top birds.
If the only line you can find of your given va-riety has many
deleterious problems alongwith their highly developed phenotype
traits,you may want to look to another variety oreven another breed
to bring in the phenotypetraits you need. While that may mean you
haveto work a little harder to get to your goal, orit might take an
extra generation or two, youwill at least not have brought in
traits that willeventually undermine your work and yourlines
integrity.
Now, I would like to give an example ofwhat I mean by the above
paragraph. If youhave a line of hatchery White Cochin bantamsand
need to make an outcross in order to im-prove the level of fluff in
your line, but theonly white lines you find also have very lowegg
production, possibly fertility issues and/or high susceptibility to
a disease such asMareks, then you may want to look at
othervarieties of Cochin bantams in order to findone with the level
of fluff you want, but thathas better intangible traits. Since the
WhiteCochin is based on standard recessive white(c/c), it really
doesnt matter exactly whatcolors are under the recessive white.
Whilemost White Cochins are actually black underthe recessive
white, there can be other col-ors under the recessive white and the
finished,recessive white homozygote will still be aWhite Cochin.
This is one of the reason thatrecessive white lines are very
popular - theyare very easy to make outcrosses with becauseonce you
get back to homozygous for reces-sive white, they are again the
variety. Forthis reason, recessive white lines can be keptboth very
genetically diverse and be a reser-voir of fine intangible traits.
The sad truththough is that very few recessive white linesrepresent
such an ideal, perhaps due to fearof outcrossing.
There are many other examples I could giveof going outside of
variety or even breed inan outcrossing experiment, but for this
articleto remain a suitable length, we need to moveon from this
particular aspect. Let me finishthis section by simply saying that
you shouldbe picky in choosing an outcross and dont beafraid to go
outside of variety or breed, butdo attempt to make intelligent
choices. Thatis to say, try to bring in as few undesirablegenes as
possible (whether alternate pheno-type genes or lack of good
intangible traits).

Even a cursory understanding of the basicgenetics of
color/pattern (1) and form/feath-ering (2) genes will help you to
avoid pitfallsand unwise outcrosses.
Once you have chosen a line to use as youroutcross, you will
want to obtain birds. In manyinstances you may be able toget a pair
or trio of the desiredoutcross material, but if youcant get both
sexes, generallyone or more cockerels of thedesired outcross will
work,though there are instanceswhere sex-linked genes maymake a
female of the outcrossstrain more desirable. If thatis the case,
even if you cantobtain a female, the male willstill work, though
you mayhave to go one extra genera-tion of backcrossing to set
thedesired sex-linked trait andeliminate the undesirable sex-linked
trait, if you use a malecarrying a sex-linked trait youdont
want.
It is so important to re-member that when you crosstwo
individuals that are different genetically,the offspring are a
combination of both lines.Generally, when we outcross, we are
hopingto bring one or more genes into our own line,but the reality
is that we bring every gene inthe alternate line into our own line
throughthe outcross, at least in the first generation.Our job then
is to both take care in what webring in and to then work to
eliminate thetraits we dont want. There are pitfalls to thisof
course. Some genes that we may want canbe linked to genes we dont
want. This can becorrected through breaking of the linkage ifenough
chicks are raised, but the worst-casescenario is when two traits
are actually theaction of pleiotropy of one gene that showsmore
than one effect. In that instance, the twotraits cannot be
separated, as they are the ac-tion of one gene. Luckily, pleiotropy
is muchmore rare than linkage.
We have already discussed the possibilityof bringing in
deleterious genes through anoutcross. This is much more common
thanwe might imagine as inbreeding brings del-eterious recessive
genes to the surface, andlines with highly concentrated
phenotypetraits generally represent fairly high levelsof
inbreeding. Thus, if the breeder(s) of thesehighly developed lines
have not paid close at-tention to the surfacing and appearance
ofdeleterious recessives, such lines can harbormany such traits. It
should also be mentionedthat outcrosses are often made to bring
in
new blood when inbreeding depression isbeginning to appear.
However, I must men-tion that the outcross of two highly
inbredlines may offer very little improvement be-yond a bit of
hybrid vigor in the F1. That isbecause such highly inbred lines,
when
crossed, may have little ge-netic diversity to offer toeach
other and many of thedeleterious recessives maybe carried by both
lines.Such crosses do little tohelp and may actually causemore
problems in later gen-erations, especially if eachline crossed
carried a num-ber of unique deleteriousfactors in addition to
thecommon ones both shared.Later generations couldend up expressing
many orall of the deleterious traitsfrom both lines in the ini-tial
outcross. In that in-stance, you end up with abigger mess than
youstarted with. Be warned andmake sound judgments in
choosing outcross materials! Dont just pickthem because they are
pretty.
It would be a truly simple thing if we couldjust extract the
desired gene(s) we want toadd and then insert those genes into our
line,and while that may be feasible for some ge-neticists in the
lab, it isnot feasible for most ofus. So we have to stumblealong
with the moreprimitive and less preciseprocess of breeding.
Thatmakes it more difficult toget exactly the gene(s) weare after
while excludingthose we are not after, butit can be done. Of
course,the key is to breed inenough numbers to seethe gene
segregations wewant. If we are doing asimple outcross, say ofthe
same varieties of agiven breed and only wantto add some
intensifiedmodifications of a trait wealready have, that is
veryeasy, but if we are dealingwith many different traitsbetween
the two lines, the job becomes morecomplicated and we need to look
toward largenumbers to get our desired combination.
One potential mistake that is frequently
made in outcrossing is to make the initialoutcross and then to
do only backcrosses toone line or the other, thinking that this
willallow us to bring the desired gene(s) into ourown line. The
idea here is to get back to thebetter line as quickly as possible
and to onlybring in the one trait to that line from theoutcrossed
line, but this is rarely effectiveor realistic. It may be more
realistic whendealing with a dominant autosomal gene, butis not a
good path when dealing with a majordominant gene with many minor
modifyinggenes or with recessive genes, as the reces-sives can
easily be lost, while the minormodifiers for the major gene can
also be lostin this way resulting in reduced intensifica-tion of
the given trait. Further, the positiveeffects of outcrossing can
easily be lostthrough strictly backcrossing, especially ifthe point
of the backcross is to bring in ge-netic diversity. However,
backcrossing of thisnature can work well if the only desire is
tobring in a single, simple, unmodified domi-nant gene like
Andalusian Blue (Bl) where theexhibition form is one dose of the
dominantgene (the heterozygote). In most casesthough, after the
initial outcross, both back-crossing and interse mating of the F1
(i.e.,F1 x F1) are advised. In this way, you can ex-ploit the best
traits of both lines, concentratethem and seek the desired
recombinants atthe same time.
First, let me state that the actual systemsof pairings one might
choose will be identi-
cal to those described in part2 such as Pair Mating,
MalePedigree, Female Pedigree,or Group Mating, etc. Typi-cally,
when we make our firstoutcross, we will be mating acockerel of the
new line ontofemales of our own line, butthere are instances, of
course,where we may bring the newline in through females of
thealternate line. This willchange the mitochondrialDNA of our line
though, whilethe use of males of the alter-nate line will not,
though thatmight not actually mattermuch and if the alternate
linehas better producing females,then we may even want tochange
over to their MtDNA.Much will depend on what isactually available
to us for out-
crossing.The first generation cross can tell us a great
deal. If we do not know the gene action (domi-nance or
recessiveness) of the trait or traits
It would be a trulysimple thing if we couldjust extract the
desiredgene(s) we want to addand then insert thosegenes into our
line, andwhile that may be fea-sible for some geneticistsin the
lab, it is not fea-sible for most of us. Sowe have to stumble
alongwith the more primitiveand less precise processof breeding. .
.
All exhibition lines as weknow them have been cre-ated in the
last two centu-ries or less. Before the ad-vent of exhibition in
the mid-nineteenth century, therewere no exhibition lines,only
landraces. From thatwe can surmise that breed-ing up an average
line intoa highly developed exhibi-tion line is a far lesser
en-deavor than what our pre-decessors did in the late1800s and
early 1900s.

we want to bring into our line, the F1 willreveal much to us. If
the desired trait(s) wewant seem to disappear in the F1 that
tendsto indicate recessive genes. If the F1 showsmore expression of
the desired trait(s) thanour own line does, then weare dealing with
dominantgenes. Further, it is impor-tant to closely observe theF1
to see if there are anydeleterious traits that haveemerged from the
blendingof the two lines. We tend tothink of deleterious traits
asemerging from inbreedingwithin a closely relatedgroup, but there
are in-stances where the cross oftwo unrelated lines can al-low
deleterious traits toemerge in their offspring.This is rare,
however, but itshould be watched for, es-pecially in regards to
repro-ductive and disease resis-tance traits. Do rememberthat any
hybrid vigor you seein the F1 will be lost, forthe most part, when
we interbreed the F1 orbackcross them to either of the parent
linesso it is hard to evaluate the F1 for vigor. How-ever, if there
is no increased vigor in the F1,then we can surmise that there are
many iden-tical genes in both lines, even if there are sig-nificant
differences in phenotype expression.Always remember that phenotype
genes arejust a small segment of the overall genomeof any gene
group or individual.
Once we have made our initial outcrossand have produced a group
of first genera-tion (F1) chicks, then we must decide how
toproceed. The most thorough path is to dothree things - breed some
of the F1 to eachother, and backcross some of the F1 to bothof the
parent lines. This will then give thegreatest possible range of
materials for thesecond generation (F2 - or technically bothF2 and
BC1 in both directions if you do allthree matings). The F2
(produced by inter-breeding the F1) gives you the opportunityto see
a true melding of the two lines and mayallow you to find many
recombinations of thegenes of each base line. With luck, you
willfind a few that are close to what you are seek-ing, especially
if you raise sufficient num-bers (which will vary, depending on how
manyalternate genes there are between the twolines). The BC1 from
breeding the F1 backto your own line may reveal some
importantinformation, the most important beingwhether you will
easily be able to transfer
the desired traits into your line through back-crossing. This is
important to know and canhelp you in deciding how to proceed.
Back-crossing to the new line that you have broughtin can also help
you in many ways, especially
in allowing you to maintainsome stock that has the de-sired
traits from that lineconcentrated as a reservoirof the traits in
case youloose the original outcrossline. The most importantthings
you will learn fromboth outcrosses is about thenature of the genes
you wantto bring in as well as to po-tentially reveal any prob-lems
in the new line you areoutcrossing to. Last, but notleast, you will
potentiallyfind the gene combinationsyou are seeking in any ofthese
three breedings withyour F1.
There are reasons tomake all three breedingswith the F1, if
possible. Oneof the most important is
that you get to see how each line (yours andthe new outcross
line) integrate into eachother. This is of course done through
thebackcrosses. When you have created eachBC1, going in both
directions by taking theF1 back to each parent line, you will see
howmuch the genes of each line influence theother. This tells you
how much dominance/recessiveness each line carries and how easyit
will be to get back to one type or the other.Of greatest relevance
is how the offspringcome out from the F1 x your original line,
asthat will show you if you can just carry thenew genes into your
line withease or not. The backcross ofthe F1 to the outcross
linewill reveal if the lesser traitsof your line will
stronglydominate over the more con-centrated traits of the
out-cross line. This is importantbecause it will tell us muchabout
how we have to pro-ceed.
The interse mating of theF1 x F1 is where we are look-ing for
the blending you arehoping to achieve, but thebackcrosses are also
important. If at all pos-sible, try all three matings. If your
space isvery limited, then just do the backcross toyour own line
and the interse mating betweensome of the F1. If you can only do
one mat-
ing and you are dealing with dominant genes(which should be
obvious from looking at theresults in the F1), try the backcross to
yourline first, but keep enough F1 to also makean inter-mating of
the F1 at a later date if theresults of the backcross to your line
arentwhat you had hoped for. It is always a goodidea to keep backup
individuals anyhow andthe F1 are often quite important to
keeparound, though they are also the generationmost people are
quickest to get rid of. Whenmaking outcrosses, I personally like to
keepthe handful of very best F1 around for as longas they remain
fertile, because they are astorehouse of genes from both lines. It
is alsoa good idea to keep an individual or two ofthe outcross line
around if you possibly can,even if you arent planning to make the
BC1of the F1 x outcross strain. At some point,you may need to
remake the initial cross, oreven a few generations down the line,
youmay need to use the outcross line again tocross back into the
later generation stockderiving from the initial outcross,
regardlessof exactly what route you have taken to ar-rive at them.
Finally, it is a good idea to keepa few of your line going pure as
well, as youmay need them again later as well.
It is important to remember that when wemake an outcross we are
changing the line.The only way to make the outcrossed linelook like
one line or the other is to back-cross into that line repeatedly
until we cometo a point where the features we have broughtin from
the alternate line are swamped andlost in the genes of the line
that is back-crossed into, but we must remember that evenafter many
generations of backcrossing, therewill still potentially be genes
there that aredifferent than the main pure lines genes. Forhobby
purposes, that probably doesnt mat-
ter much, but it is still somethingto be aware of. Repeated
back-crossing though may cause thegenes you want to bring in to
beswamped in the genes of thebackcrossed line. This is espe-cially
relevant if the genes youare after are not visually identi-fiable
genes, but are insteadgenes that effect fertility, chickviability,
production or genes thatare recessive. If you are out-crossing to
bring in these typesof genes, then only doing re-peated backcross
to that line
lacking these traits will quickly see thosegenes lost. In such
instances, the mating ofF1 x F1 is the most important of the
poten-tial crosses to make, as this will usually al-low the actual
shuffling of genes and the po-
Once we have madeour initial outcross andhave produced a group

proceed. Themost thorough path is todo three things - breedsome of
the F1 to eachother, and backcrosssome of the F1 to both ofthe
parent lines. This willthen give the greatest pos-sible range of
materials forthe second generation.

tential recombination that you want - i.e., aparticular look
with a particular set of per-formance and reproductive traits.
In complicated outcross work, where manyfactors are to be
brought in, it should now beobvious that multiple direc-tions will
be necessary. Verycomplicated breeding pro-grams, such as those
that re-quire a very specific set ofphenotype traits along with
aspecific set of performancetraits may require manycrosses, with
outcrosses,backcrosses and multigen-erational backcrossing inboth
directions all beingused. While such projectsmay be beyond the
scope ofmost hobbyists, it is still use-ful to be aware of what
ispossible given space and re-sources. Most any combina-tion of
traits can be com-bined with patience and largenumbers. Any breed
can haveproduction traits and diseaseresistance added to
themwithout destroying the type, if the breeder iswilling to make
the effort and raise the num-bers to achieve the goal.
For the average hobbyist who has beenworking with hatchery stock
and wants to im-prove their phenotype traits, you are embark-ing on
an exciting project that is the basis ofall breeding. At one time
or another, all exhi-bition lines have been bred up from
lesserstock, even if we have to go back a century or

like oneline or the other is to back-cross into that line
repeat-edly until we come to apoint where the featureswe have
brought in fromthe alternate l ine areswamped and lost in thegenes
of the line that isbackcrossed into . . .
two. All exhibition lines as we know them havebeen created in
the last two centuries or less.Before the advent of exhibition in
the mid-nineteenth century, there were no exhibitionlines, only
landraces. From that we can sur-
mise that breeding up an av-erage line into a highly de-veloped
exhibition line is afar lesser endeavor thanwhat our predecessors
did inthe late 1800s and early1900s. In addition to ourhatchery
stock being farmore developed than thelandraces the exhibitionlines
were developed from,highly concentrated exhibi-tion lines already
exist anddo not have to be madefrom scratch as was the casein the
early days of exhibi-tion. Add to that our under-standing of
genetics andbreeding, and we are in a farbetter state to achieve
ourgoals. All you have to do ismate the birds, raise suffi-cient
offspring and use se-
lection, as is the basis for all breeding.(1) - See An

On Wednesday, May 28, 2014, I enjoyeda positive meeting with Dr.
Robbins, Dr. Stacy,Dr. Barrington, and John Walther. I was toldthat
at this time only birds crossing the stateline into Louisiana
require a Health Certifi-cate and Form VS 9-2. Form VS 9-2
(attached)shows the flock is NPIP certified free of sal-monella
pullorum and typhoid or the birdshave tested negative for
pullorum/typhoidwithin 30 days of entry. State residents do nothave
to have a Health Certificate to showwithin the state, but they must
have a FormVS 9-2 (or have an NPIP certified flock)showing the
birds have tested negative forpullorum/typhoid within the past 90
days.However, LSU AgCenter Shows (4-H, FFA)still require both
health certificates and NPIPpullorum/typhoid testing.
Dr. Robbins is also studying the possibil-ity of having the
shows hire a private, accred-ited veterinarian to check birds at
our showsas an option. Dr. Robbins did stress that indi-viduals
going to another state for a show mustmeet the entry requirements
for that state, aseach states requirements are different. He
issupposed to get back with me by the end ofJune.
