It has been a very long time since I had to deal with this. This morning when I was feeding my birds I noticed a hen constantly shaking her head. One close look and I could see that she was infested with small, quick moving, dark looking parasites-Mites? What is the current treatment? My biggest concern is for my hens that are brooding; one is due to hatch chicks this week. What is the best way to treat a broody who will be hatching soon?
