Hello out there! I am the proud owner of three Brahma hens today! We have a nice little coop in our backyard, and i'm worried about mites. One of my hens is constantly pecking under her wings. I've read a lot about DE and sevin dust and am a little confused by the whole thing. Do I bath them, just dust their run and house or put it in their food? Should I dust the area around their coop as well? They must have brought the mites with them. They're about 8 weeks old, and are on Purina Start n' Grow Medicated food. Should the medicated food take care of mites? Any suggestions would really help me out! Like I said, I'm brand new to chickens and BYC (so I hope I'm doing this post right Thanks guys.
