I noticed when I went out to feed this morning that one of my 19 week Buff Orps has a dangling wing. Things have been getting pretty rowdy in the coop the last few nights, so we put in another roost to add more room, and maybe alleviate the squabbling at night. They free range during the day, only in their coop from dusk till dawn. Could this have happened from being thrown from the roost? It's only about 18" above the poop board. Could it just be sprained? If broken, what is to be done with it?
