I just went out to collect eggs and noticed my rooster is missing a bunch of fluff feathers, just below his tail feathers on his bum. The skin is not inflamed at all and nobody else is missing feathers. I have 1 roo and 9 hens. I'm not sure but, I'm thinking this is from him breeding the hens so much? I'll try to get a pic but, he is not very co-operative lol.
