Yuuuuk! This is a first for me! I'm sure it's occurred before, but I neglected to notice. Probably the reason I noticed my birds are infested now is because I can see the red mites now following recent cataract surgery. I dusted the flock yesterday with a poultry dust containing pemethrin, and it made the bugs run for their lives. But now the chickens are left with a cement-like coating of red mite eggs on their feather shafts. How do I get rid of this crud? How long before the eggs hatch and will this "cement" slough off?
