I have a really huge problems with mites in my coop and on my chickens! At one point I was treating them weekly with poultry dust but the problem is so bad that I couldn't rid the chickens of the mites! I discovered that they were nesting within the cracks of the wood in my coop and they are massive amounts of them in there! I covered the wood with lime for trees but still can't fix it! I've gotten to the point where they are making their way into my trailer! Any other effective solutions without having to cull my birds or burn the coop?
