We have just recently received some chicks it is our first time with any chickens at all. About 1 week having them they started to peck at each other and 4 of them are hurt. 3 of them are just small wounds and nothing too big but the 4th one is hurt pretty bad, she has a hurt upper right wing and I can see her bones.She is just sitting there not moving much. I have them all separated into there own cages with their own lamps with food and water but I don't know much about them and I don't know what else to do for them. Any help would be greatly appreciated.
