In a few moments I’m cleaning out the coop to prepare to apply permethrin dust. I will be dusting the birds later. I keep reading how to apply to the birds but very little about the coop. Mostly it says apply into cracks and crevices. Some say apply to nest boxes. Others say never apply to nest boxes. Nothing is said about dust bathing boxes. The container has sqft information but if I can’t put it in nests should I not put it in areas that are exposed to inquisitive chickens? I would have preferred to use Elector PSP but it’s too cold to be dipping chickens in water. I saw one very tiny almost translucent white bug run on a chickens belly. No eggs seen yet but I haven’t inspected everyone yet. Any advice?
