So I have this 1 year old hen who attacks the chicks I have in the coop ATM. She will go after them even if they aren't near her. The coop is big enough and she has two older hens that she gets along just fine with. One of the babies got out today and is now bloated and has a gigantic hole on his neck. I'm pretty sure he isn't going to make it through the night. I have 12 chicks coming in compared to 3 big hens. ( the other two hens could care less about the babies, but the mean hen just won't leave them alone.) is there anything I can do to keep her from pecking, or do I have to regime her? I would rather lose one hen then all my babies.
