Have you cleaned or flushed the wounds at all? You will probably be able to tell more once you clean and flush the wound. Use Chlorhexidine (Hibiclen) or Saline to flush the wound. Trim the feathers away from the wound so you can see it better. Apply triple antibiotic ointment to the wound to keep it moist.
