One of my hens was horribly injured, mating injury.  Her whole side is skinned.  Hard to treat these wounds because, as I have found out, no subcutaneous tissue under the skin.  Well, I guess I knew that about chickens, as anyone who has removed skin from a chicken breast can see, but I never thought about how thin the skin is in relation to a live chicken with an injury.  Until I had live chickens.  And by the time I discovered the injury, it was too late to bring up the skin and suture it back into place.  It was shriveled and dry around the edges, no longer healthy tissue.   It is open to exposed muscle.  So, I mixed up a batch of 100 ppm hypochlorous acid and I am spraying it twice a day, but I am not keeping it moist enough for my liking, in order for new tissue to granulate in.  Saline-soaked gauze or hypochlorous acid-soaked gauze is an option but hard to keep in place unless i wrap her all up.  I suppose I could run up to the tack shop and get some vet wrap...  Right now, she is pretty perky after 3 days of treatment.  I was wishing I had some hydrocolloid to put over her exposed wound and thinking I would never find it but they do sell it on Amazon.  I thought it might be prescription only but no, it is not. It is basically a gel that sticks to wound, absorbs extra fluid and keeps everything moist which promotes healing.  They sell hydrocolloid bandages for heel blisters and burns which I have used personally, but I just bought the 4x4 squares and a roll of hydrocolloid without surrounding adhesive because I dont want the adhesive.  I don't want adhesive sticking to the muscle.  I am hoping it helps her heal faster and encourages new growth of healthy tissue.  Hydrocolloid would be hard to put around feathers on a wing, I think, because it has to make contact with the wound bed and the feathers are in the way, but since I have a large area to work on that is featherless, I am going to give it a try.   I don't know if it will work.  I have no idea if it will stick.   I am winging it here.  Before I apply it, I am going to gently scrub the area to get down to healthy tissue and try to eliminate any dried nonviable tissue.  Then a generous spray with hypochlorous acid, then the hydrocolloid, repeat as needed, then wait and see.  I will post again if it works.  The rooster is rehomed in his new bachelor pad.
