Well I was just telling my DH how well our transition went for our chicks. We had seperated the coop so the chicks were isolated from the hens. Well they figured a way out, and got into the pasture with the hens. I thought all was well as there was plenty of room and the chicks stayed away from the hens. I just went out and my 7 week old white leghorn has the skin from her back of the neck ripped off. She isn't bleeding but you can clearly see muscles, bone and veins. She is eating, walking and drinking fine. What should I do? I have a rabbit hutch I can put her in...Do I cull or treat? Is this the work of a roo or my dominant hen? Do I have to seperate them all, will they attack my other babies? *update*I have patched up the coop, so everyone is seperated again. And the injured white leghorn (*Sugar, is her name*) is in the rabbit hutch with one baby bunny. I gave her some food and she is acting normal. But I am unsure how to treat her. Will the skin ever come together or regrow?
