I have a naked neck rooster and 7 naked neck hens. They are not pure naked necks. I imagine they have been crossed with whomever many a time. I only have NNs, no other chickens. I was graced with 4 chicks this past year. Only one of them has a naked neck! I thought NN was the dominant gene so even if a half NN mated with another half NN they would all have naked necks. Can anyone explain? Thank you!
