We have two roosters, an EE and a RIR.. and then we have RIR hens, EE hens, and BO hens. Somehow, a brood hatched out what looks like a meat bird- EE mix... When he was a chick he was yellow, with BRIGHT yellow feet, and he looked like a meat bird. But with muffs. He did hatch out of a green egg, so he is some sort of EE cross. We have hatched out tons of our chickens and never got a white one. He is seven months old now, and still looks like a muffed meat bird. Fat, has a hard time walking... still PURE white with no feathers on his breast. Not a pretty roo. I did have two free range meat bird roosters, around 8 months, but I heard that they can not breed.
