I have a black cochin rooster I somehow ended up with him from some tsc chicks a few years back. He is adorable and he's also the only rooster I have in my flock the rest are EE, BO, BR hens who have all gone broody from time to time and have never got any chicks? I know this is going to be a stupid question but can he mate with regular hens or could he just be sterile?
