Our girls have been banged up for several weeks now which they seemed to take to with no problems. Yesterday OH saw Morag, our cuckoo Marans, who is the boldest of the trio, swipe a feather from Skye's bum and eat it. She's been at it again today and the other two run away from her, as far as they can. I don't know what to do. We didn't notice this behaviour when they were free ranging. We don't have another coop to put her in and it's flippin' cold at the moment..
