I have 8 five week old white silkies that i bought from ideal as day old chicks. They've gotten out of there awkward phase. There even starting to get out of that ugly phase. Everything was nice and happy til one of my chicks started pecking abusively at the rest. In the past week they have been establishing the pecking order. The have been jumping at one another and maybe a peck or two. But this guy has crossed the line. He grabs the by the neck and holds even after the other chicks starts to run and cry. So i took immediate action. i set up a make shift brooder so he can have alone time. I read that this is a good technique on abusive older birds. Hes right next to the other guys brooder. Should i move it further so that they can't see each other at all? Should I rehome or cull or keep trying to work on his behavior? I've never culled a chicken before but this guy wouldn't make it too hard. So please give me advice. What should I do?
