My little banty rooster has been being picked on by my big rooster...but he doesn't just run away, he fights back. Anyway, this has been going on for a few days. He's lost a lot of neck feathers, and today he apparently ripped a toenail backwards and now it's just hanging there and he is bleeding. It's not like it's gushing blood, but it is bleeding enough that he's mangaged to wipe it all over his other leg. I'm worried that now he'll get picked on even more. Any ideas? I only have the one coop and it's snowing here so I can't kick anyone out.
