I use a slow grow cornish cross in my mad experiments.Ive gotten some impressive birds.
What do they give to the cross?

I'm really hoping that one is pure. If he is, I'll put him to good use. If not, he'll feed the family.
Some of the others are smaller but with the same characteristics.
Heello aviangems this just my problem , i have been looking 4 a way to get these Cornish chickens and many more breeds how can u help me
So if you had the Columbia gene and the Black Lacing Gene on a dominant white or recessive white, would either of them be white with black single lacing?Genetics 101
No- if they are dominant white then the hypostatic color would be black with the epistatic color being dominant white. Dominant white birds can be black, barred, mottled, blue or even splash under the white. Most likely your whites are recessive white- then the cornish can be just about any phenotype under the white.
In order to produce jubilee in the F1 generation one would have to cross a jubilee with a dark cornish. Then all of the offspring will be jubilee or 1/2 will be jubilee and 1/2 dark cornish.
I have worked with dark cornish some and produced some almost black birds through selective breeding. I can not remember the research article but others have produced blacks from the dark phenotype through selective breeding. Dark cornish are supposed to be recessive wheaten but I think some carry the brown allele and when it segregates you get the very dark almost black birds, I could be wrong and it is something else.
Jubilee are a dominant white dark phenotype but if the whites are dominant white then the dominant genes for black color in the whites when crossed with dark cornish will produce F1 birds that are epistatic white ( some may leak red).
The F2 generation could include jubilee or even false standard red pyle males but the probabilities are not in favor of that happening. Females will not be standard red pyle because they are not wild type at the E locus. It all depends on the number of chicks that are hatched.
The male in the back of this picture is leaking red in his hackles- that is an indication he is most likely dominant white and not recessive white. He also has a black spot showing. With that said, most recessive white genes are not leaky but there are documented cases of leaky recessive white alleles.
The birds in this picture are also leaking some red. Could also be a red pigment from clay. The owner may make comment on the birds.
