A couple of weeks ago , I received a rather alarmed text edition from my friend Rose , who keeps a little flock of chicken in Idaho . “ WHERE’D HE COME FROM??!!!!!”read the message .
It was keep company by a exposure of a a quintet of fluffy baby , perhaps 3 day old at the most . Amongst the endearing black peep stand one oddball : a slate - drab fluff . Rose had purchase a half dozen hatch testicle to hatch from a neighbor who purportedly only raised black chickens .
“ Is he an albino ? ” she asked , baffled by the picayune puritanic baby .
Thus was Rose innovate to the ofttimes mystifying populace of poultry coloration genetics , where blue , white , and lavender can come from black ; where black can hail from blue ; and where partisan speak in unusual notation such as ( Bl / bl+ ) , ( Pg ) , and ( Co ) .
While the average backyard chicken - keeper is commonly not looking for a moral in genetics , consume a canonical noesis of poultry colour genetics is a worthful tool as it can aid be after out a beautiful change of birds or aid in producing specific chicks for sale .
On our farm , we concentre on blue - pitch-dark - splash ( BBS ) birds . This allows for a form of colors in our flock without risking a woolly-headed mix that might result should a buff rooster cover a black biddy .

All You Need to Know About Genes
A gene is a section of DNA that carries the blueprint for such traits as colouring material . Austrian scientist Gregor Mendel discovered the winder to hereditary traits through his studies in the mid-1800s .
Mendel ’s Laws of Inheritancestate that cistron occur in pairs and that each parent contributes one gene to that pair . That cistron pair determines how the hereditary trait manifest in the offspring .
When a cock and the biddy contribute both give Gene A , the genic state is calledhomozygous(homo- comes from the Greek word entail “ the same ” ) . When a cock give Gene A and a hen contribute Gene B , the genetic United States Department of State is calledheterozygous(hetero- add up from the Greek word mean “ different ” ) .

Dominant, Codominant & Recessive Genes
cistron can be either dominant ( manifesting in both homozygous and heterozygous states ) orrecessive(manifesting only in the homozygous state ) .
If a rooster ’s Gene A and a hen ’s Gene A are both dominant , the result would behomozygous dominant(same genetic state ) offspring AA . But if a rooster ’s Gene a and a biddy ’s Gene a are both recessive , the result would behomozygous recessiveoffspring Associate in Arts .
If a cock ’s Gene A is dominant and a hen ’s Gene a is recessive , the termination would beheterozygous offspringAa . However , if a rooster ’s Gene A and a biddy ’s Gene B are both rife , the issue would becodominantoffspring AB , showing both colors as .
In poultry genetics , both black ( BB ) and white-hot ( WW ) are dominant . So breeding a black rooster with a clean biddy would result in a black - and - white Gallus gallus .
The Blue-Black-Splash Coloration
In colour genetic science , the genetic code Bb represents dingy while the genetic code for black is BB . The ‘ b ’ comes from splash ( genetic code bb ) . Splash coloration in chickens manifest as a white or very muted grey ( in other word of honor , black ) ‘ splosh ’ with temporary splotches of black or blue .
plash wimp are beautiful , optic - catching birds and are often in high demand . I once had a client who repeatedly ask to buy a dozen splash wench … which is not as easy to engender as it sounds .
These four cosmetic chicken breeds add some wow factor to the flock .
Breeding Blue-Black-Splash Birds
When it comes to breeding for Blue Black Splash , gender does not matter . These colors are not sex link up .
The rooster and biddy can be any of these three colors . What does count is which color the parent birds are , though . This will find out the percentage of the blue - black - splash coloring in the chick :
As it turned out , Rose ’s egg seller did have a gloomy hen in his flock . This , then , explain how the mystery frippery appeared in her incubator .
Not that she minds . She be after on get more hatching eggs from her neighbor with the hopes of cover more blues that , down the line , may someday yield spattering chicks .
