I usually leave wounds like that alone to heal on their own, which they usually do, as long as the birds are not suffering. If they are deep, leave them, superficial ones I will spray some bluekote on them. Keep them separated but within sight of the flock until they heal enough to not draw attention to them. If the wounds are really bad it's best to cull.
Chickens, muscovy ducks, turkeys, donkeys , goats, dogs, fish, parakeets, a parrot, and a cat.
