I hope I am not bringing up an already-discussed topic. I need help with getting rid of mites in my flock, I have 19 hens and a rooster, and 10 quails in a separate coop. Most are different colors of Brahma and a few New Hampshire reds and a few Ausralorps. I had a mite infestation that took the life of one of my hens. I have sprayed their coop and run with Permethrin (1 to 20) and dusted them all with Permethrin powder 3 times 8 and 10 days apart, things have improved, they started laying again (in middle of winter), and eating more, but the mites are still around and sometimes I feel them on me. Please help. I live in Northern California.
