Hello, Have you ever wondered? I have three blue Cochin's. I think it is funny how one is white\blue, one is all blue and one is black and their the same breed. If a white Cochin hen and rooster breed, is it possible to be all blue or black? I always think of that. -The Angry Hen
Cochins come in almost all color- they can even be barred like a barred rock. I don't know anything about the color genetics behind them but, if you post your question at "What breed or gender is this." Someone will be likely to explain it for you.
