Obviously this isn't a huge problem since I haven't seen it mentioned anywhere, but I had a thought. How is it not a problem that chickens will clean themselves and eat the mites moving in overdrive after sevin dust, or whatever your choice of product, is applied? I used Viper Dust, the only thing the local place had today. I used all the nifty little tips found on this forum and things went pretty smoothly. I'm still a bit paranoid about having to have used anything, but we have to do what we have to do right?
