Sevin dust is in the gardening section usually. It is a pesticide. If you find mites and need to dust the chickens dust their coop, too. Use it sparingly and don't inhale it and try not to made it too dusty because the birds will be inhaling the dust as well.
When I get a new bird I mix a little DE and the Sevin and powder them all down - just to be on the safe side.
