Our chicks were attacked by (we think) a raccoon. Three survived, one has a broken wing, with bone showing. She is still running around with the other two. What do I do for this? It is scary.
Put some weak betadine on the open wound, then Neosporin ointment when it is mostly dry. Cover the wound with telfa or gauze. I have no experience with broken wings other than to wrap the broken wing in a normal position against the the body with vet wrap or Coban from the drug store. Don't wrap too tight or they won't be able to breathe. On Monday, I would take the chick into the vet so they can take care of the protruding bone.
