I have a Cochin who can't open its eyes. My husband said one of the Wyandottes had been pecking at its eyes earlier that day. I have 15 chicks in one brooder. Should I remove the Cochin and put it with a few other mellow chicks in a separate brooder? Is this something that happens a lot with chickens? When I first got them it seemed to be something they did often but not excessively.
