I love giving my chickens a dawn dish soap bath! I'm currently dealing with mites and when I give them a bath with dawn it gets almost all of them off! Of course a bath probably won't get all the mites off but baths do really help!If you don't see any but your still worried give them a warm dawn dish soap bath. Kills whatever bugs might be on them and completely safe for chickens. Search up how to give them a bath and you'll do great.
