I got 8 Ameraucana chicks (about a week and a half old) this weekend from a farm auction. One of the little darlings is not a darling. It pecks the other chicks very hard. Their little cheeps can be heard throughout the house. And it seems especially interested in backsides. Pecking two other chicks until they were bleeding. I separated it from the the rest. Can I expect it's behavior to get better? Is there anything else I can do?
