I recently discovered lice all over my chickens after seeing extreme feather loss around their necks. So I bought Prozap and I started cleaning out the bedding (hay). While clean out the bedding and taking out old wooden nesting boexes, guess what else I believe I found, mites... tiny and black, looks like moving grains of pepper. I know mites are a bigger problem and I need advice on how to treat them cause my situation is a bit different then your average chicken coop. Our "coop" is a bunch of the big 6 feet tall dog kennel panels put together in our barn. The coop is 6 feet wide and about 30 feet long, and the chickens free range every other day from 3 to dusk. There are 21 chickens, and a section of of the coop is blocked off for 6 chicks ranging in 5 - 8 weeks. The reason I don't know how to treat, is that it's literally a giant metal dog kennel with wood and hay inside and out, surrouding the coop is piles of wood and haybales. I can't remove all the hay bales and wood and treat the entire barn. So any suggestions? Please don't be afraid to speak your mind, as my chickens have had these bugs bad for a while now and need the treatment soon, and they are loved pets so I don't want to lose any of them. Thanks.
