So, after MUCH research, I found a non toxic remedy for mites. I WILL NOT use pesticides. I ordered Poultry Protector (thank you whoever it was on BYC that turned me on to the product) and received it today. I began bathing the chickens and dipping them in a poultry protector bath. The mites left over in the tub were DISGUSTING! I set the first three in a tupperware tub with a heat lamp and blow dryer and began scrubbing the coop. I found TONS of mites nesting all over the egg boxes. I thought I was doing an incredible job keeping my coop clean, but I was WRONG! I thoroughly scrubbed and sprayed the ENTIRE coop and burned the bedding. I had been using DE, but apparently that was not enough. Tomorrow, I will be bathing and dipping the remaining 20 birds. Hopefully that will get things back under control. I now know so much more about organically contollng pests and figured out where they like to breed. There is certainly a lot more involved with chicken keeping than I thought, but love taking care of my birds. I'm glad I caught the problem early.
