I've had birds pick at each other in a small kennel while traveling. Hopefully your coop is big enough to give them room to escape from each other. Make sure are lots of roosts and things around to distract them. Make sure to use something on the wound...as Bairo said, blu-kote or something similar can camoflauge it so the others dont pick. Its possible you may need to lock up the "bully" (or bullies) temporarily to let the others get higher in the flock. Do you have other hens? That may change what we recommend.
If they are in a larger space (ie a coop versus a travel cage), they may get along better. my birds all get along great in a half acre area. But if you stuck them all in a crate, they would fight. That's just what they do.
