Hi all, I have about 20 chickens , about 6 silkies and the rest are bantams. Me and my daughter hold them and I've noticed I have started to itch and so has my daughter. But when she itches she looks like she has whelps on her. Anyway I'm thinking it might be mites or bugs from the chickens. What do you use on them. and what do you use in the pen. Any help will be greatly appreciated. Thanks
