    It would be best if you had a Choc male to breed to Black Cochin hens since the gene is sexlinked. I'm not sure how it would work with the choc being a hen but either way you would use blacks.

    choc hen on black cochin = F1 black offspring and only the males carry the choc gene

    Back cross the choc female to an F1 black male= some F2 choc males and F2 choc females other F2 are black

    cross choc females with a choc male = all choc

    Choc is a diluter of black, so if your bird has black it her she may not be choc. The gene doesn't affect red pigment, so you'll want to breed her to black Cochins.

    chocolate gene is simular to the blue gene.

    CHOC ROO X BLACK HENS WILL GIVE SOME CHOCOLATE OFFSPRING.

    BREED ONE OF THE F1 CHOCO SONS TO THE BLACK MOTHER FOR A LITTLE BETTER TYPE. & SO ON......

    THAT'S WHAT I WOULD DO ANYWAY. [​IMG]

    Quote:do you mean the dun gene? It's an allele of dominant white, I^d, and it works like blue......

    Quote:This is the correct information for real chocolate.

    I wouldn't use a serama for this, you will be fighting the "itty bitty" bird gene forever. Greenfire farms is supposed to be getting chocolate birds next year some time.

    Quote:Your thinking of Dun (Hobby name, "Chocolate")

    Two doses (dun splash/ khaki) breed true, so 100% Dun Splash or Khaki.

    Dun Splash x Black will give Dark Brown/ Dun (100%).
    Dun Splash x Dark Brown/ Dun gives Dun Splash (50%), Dark Brown Dun (50%).
    Dark Brown/ Dun x Dark Brown/ Dun gives Dun Splash (25%), Dark Brown/ Dun (50%) and Black (25%).
    Dark Brown/ Dun x Black gives (50%) Dark brown/ Dun and (50%) Black


    The Chocolate gene is a sex linked recessive mutant gene, so the females cannot hide the gene. If they possess the choc gene, they will be Chocolate. Males, however can be carriers and require two copies to be visually Chocolate.
