Just wondering what everyone does to help prevent/maintain flies in their coops/runs? I have chickens, quail and ducks and this year has been the worst for the little buggers in the past three years. I have disposable fly traps up in each of the coops, along with vanilla-scented car scents. (I heard flies don't like vanilla. Regardless, it helps with the fly trap smell.) The local dragonflies have also been helping me take care of the pests. Not that it will happen, but I am worried about fly strike.
