I have an all drake flock of 3. It will be almost a year since I got them as babies. Within the last two days one of my boys is all scruffy and his neck feathers are being pulled out he has a bald spot. He also has a bald spot under his wing. The other two drakes look completely fine. It seems as if both of them are bullying the one. Its so bad he runs away from the other two and sits alone in one corner of the pen. He doesnt even run when I pick him up. I know your supposed to seperate the bully but if I seperate two out of three im worried the bullied wont be able to keep warm. I live in ohio and its still cold. Suggestions please.
