Hello, New to BYC but reading for awhile, usually when in crisis over past year with new endeavor of having chickens. One of my 5 Marsh Daisy hens ended up going broody about 5 weeks ago right when my Black Jersey Giant roo got eaten by something (free range all day). Three weeks later, I awoke to 8 chicks, one eventually died. Im happy to have the heir to my roo, but Im now curious about what kind of crossbread this gonna be. Heres a pic of some of the hens and the giant. I understand its a black sex link but not much more than that. Only one has a spot on top of its head, but others have some yellow/white markings on head around eyes, while others are have all black heads. Im assuming those are the hens, and the marked head are the roosters. Is this right? ...adding pictures... What would happen if I bred the roosters back into my other Marsh Daisys? Would they be beefier hybrids? Mostly black? Hard to breed the black out? I understand there may be tons of variation in the characteristics of the progeny but would it be probable to get some good free range beasts? Is this heresy to breeders? Im suddenly interested in making my own breed that would be good for my predator pressured free range situation. Thanks for letting me voice some of these thoughts. Now I will continue to read up on breeding. I would appreciate any good books on breeding genetics of chickens.
