i am no expert on chickens and now i have a black cochin rooster that is 51/2 months old. tell me everything about them. are they friendly,make good pets and protectors that sort of thing. also my hubby says he is not a rooster because he is not crowing,hubby know nothing about chickens,but when should he start crowing. i told hubby he will either crow or lay,either is fine by me!!!
