Somehow, 3 of my 2 month old chicks got injured in their coop. We've been very puzzled thinking predator or other chicks, then looking for a place in there that they could get hurt on. 3 of them have injured one leg, one very raw and bloody, 2 others can't walk and just look like the skin is scraped but can't walk. Is there anything I can do for them? I have them isolated but they don't seem to be improving any. (We fixed one potentially hazardous place and so far-after 4 days- no more injuries.) I have washed the worst one and sprayed vet antiseptic spray. I try to move them about daily to keep them from "freezing" up but that hasn't helped. They are eating and drinking. Any hope?
