I just got a rescue hen from a friend at my dads work. She's been beaten up by other hens. I gave her a bath the next day and noticed mites on her!! I put some (not a lot) mite powder (forgot what its called) on her and in her pen. Luckily she hasn't been anywhere near the other girls! How do I get rid of these and fast!! I'm not experienced with mites!! Help!! Thanks!
