So I have this light brahma rooster who is pretty big. He mounts, or tries to, pretty much any or all of them. But there is one hen who is probably always been the naughtiest one who he picks on the most. It's gotten to the point where he's pulling out huge amounts of feathers. She's missing almost all her neck feathers and a lot on her back too. Is this one of those, let nature take its course things? Or should he be removed?
