I have a 5 month hen who started becoming lethargic two days ago . I checked her and she did not have mites but she did have a sore under one of her wings. I sprayed it with med and gave her some meds and isolated her . Today the sore was larger and it looked like maggots were on it. I put fly powder on it and I put 1/2 ml of ivermitent pour on her back. What should I clean it with in the morning and what should I do appreciate any help
