    I have a friend that is putting a Chocolate Orpington rooster over Buff Orpington hens. She's wondering what color she'll get? I figured maybe choc.with buff leakage? But I'm just guessing.

    Any thoughts would be greatly appreciated.

    No ideas? I have been trying figure out the genetics calculator, but I'm not having any luck.

    I came up with if Chocolate rooster over Buff hens=
    50% chocolate unicolor pullets
    50% black unicolor cockerels.

    Now all that I'm sure there could and will be some leakage.
    Where you go after that I'd guess take the pullets back to the chocolate father or another chocolate rooster.

    Sex linked Cross.. The Females will hatch Chocolate and males will hatch black... thats for chick down when they start feathering the females will be mostly chocolate color but will show Silver/gold leakage mostly on the breast area, the same for rooster(except they will either be gold or golden)

    here is a thread about black orp x buff orp crosses and how they look

    My husband and I are considering doing this cross. Wondering if anyone has pics of the resulting chicks? Can anyone confirm the sex link claim? The link is to black Australorp over Buff Orpingtons

    Yes this is a sex linked cross. Chocolate is a recessive sex linked trait, with the cross the male will give a choc gene to his daughters. Females only need one choc gene to express the trait while males need two choc genes. The buff hen can not give a choc gene to the male offspring, so no choc plumage color in male offspring- the male offspring will have a black ground color.

    I can not find my pictures but I made a similar cross- the male and female offspring can have varying amounts of buff on the head, breast, and hackles. They could just show some buff on the face and head or have a large amount as described in the previous sentence.

    The female offspring will have a chocolate ground color and the male offspring will have a black ground color. The chicks can be sexed at hatch.

    The genetics of the chocolate hen parent will determine if the female offspring show any secondary pattern in the plumage. The female offspring could show chocolate false spangling in the area that is buff. The female offspring may also just be buff on the head, breast and hackles with no secondary patterns.

    Male offspring should not express any secondary pattern. Birds that are black ( the chocolate bird is black but the choc gene changes black to chocolate) sometimes carry the pattern gene and melanotic which would cause the false spangling in the female offspring.
