You should also invest in a spray for their stall/coop to kill any mites that live their. I use Sevin Concentrate.Thanks, allI'll put the birds out to free range today while cleaning the pen. Every 6 months I normally pressure wash their entire stall, put some bleach in it, then wash it with water again. I'll look for some Kleen Green at Big R as well. It's supposed to be nice and warm (above freezing) today.![]()
