I would just rinse the area with soap and warm water, just pour it over, then rinse well. Then I think I would put some gauze right over the area, with a little oil or Vaseline or antibiotic ointment from the drug store. If you wrap around from the bandage up around the lower back, and go around a few times with tape, the feathers should hold the tape on. Or just keep wrapping.
Then you have time to make a decision.
