My chickens have mites! I had not noticed any symptoms, but I found bugs on an egg and then checked their vents, and they sure do have mites all right. I have ordered Prozap Garden and Poultry Duster to treat the birds and coop, but I am not sure whether I need to also treat areas they spend time in during the day. They range in the yard each day, so if mites are hopping on and off all the time they might be in the fence, the porch, the compost heap.... Is that a concern, or do mites stay where the chickens sleep? They seem pretty active in the coop during the day -- when I picked up some recently-shed feathers they crawled all over my hands (yuck). Relatedly, could they establish a colony inside the house? My research indicates that chicken mites will bite people, but I don't know whether they can live off people.
