    Hows it BYC?
    Just wondering if Golden Cuckoo Marans are an autosexing breed?

    Yes, they are. Males are lighter and females are darker.

    No, I don't. Sorry.

    Try doing a search on here and you might come up with something. [​IMG]

    Yes only if they are based on the Birchen allele, I have seen golden cuckoo based on wheaten(yellow chick down) and when based on wheaten the chick down is just yellow/cream, but when based on birchen the down is dark allowing the sex linked barring gene to do it's job(to lighten up the double barred males)

    Male on the right, females on the left
