    Ive gone to the chicken calculator and tried to plug this in, but apparently Im an idiot and can't figure it out.

    If I breed wheaton roos to cuckoo girls, it seems like the resulting girls are black. Now I really dont know how the wheaton gene (or genes) work, as in does the black hen carry a wheaton gene? What would happen if I would breed those black hens back to a wheaton? Will I ever get back to wheaton?

    The black females would carry wheaten. If you then put them back to a wheaten you would get about half wheaten offspring. However the resultant offspring will sometimes pick up other genes from the black.

    If you breed wheaten to cuckoo what you should get, I would think, is crele not black.

    Reading the post I can't tell if you have already done this or are just thinking about it. saladin

    The cuckoo is sex-linked. Cuckoo hens will pass that gene only to their sons. Crele is e+, not e^Wh, but they would look similar.

    Quote:I beleve that you would have to breed a Barred bird to a Black Breasted Red to get the Crele color..
    I know in order to get a "Intermediant" Crele you would breed a Crele to a Black Brested Red.

    If you breed wheaten to cuckoo what you should get, I would think, is crele not black.

    If you breed wheaten to cuckoo, it is a sex linked cross giving black barred males & black unbarred females (adults of both usually with leakage)
    The, expected, extended black (E) of the cuckoo is dominant to wheaten (eWh)
    Think of the black sex links. They are often RIR (wheaten based) on barred rock (extended black based) the offspring being the expected black barred males & the black unbarred females.​

    I guess I need to clarify my statement.

    The only Wheaten I know anything about is that found in Cubalayas and other Orientals: but especially in Cubalayas. Jeffery and others refer to it as recessive wheaten.

    I understand sex-link genes.

    I also understand the "normal" Crele, but you can get the same-looking bird with wheaten.

    Of course, everything that has been stated is good and true; but is all based on the purity of the sire and dame. If they have other recessive colors within their make-up there is no telling what you might get!

    Recessive wheaten has been found to be the same gene as Dominant wheaten. It just behaves differently under certain circs.

    Cuckoo on a wheaten male would look much the same as true crele (as would cuckoo on eb males), however the fames would look rather different to true crele.
