Thanks, I just got my photo to upload. After doing some research, I think it is an infestation chicken mites or lice. I plan to traet the birds with chicken dust, cleam out the coop and treat it with chlorox and water and give them a shallow tray with DE, sand and the dust to do dirt bathes in. I am also planning to provide vitamins in their water for the next two weeks to help get the feathers going again. I will post my results.
