Today I got something similar (I hope) to poultry dust called Gordon's Dairy & Livestock Dust (permethrin and says it can be used on poultry). I also ordered a 50# bag of food grade DE the other night. I have never seen any mites/bugs/lice on the chickens, but want to dust just in case. What would be my best course of action with these? Do I clean out the coop, lay new straw and then sprinkle the permethrin dust? When I get the DE, if I put it in a shallow feed tub will the chickens go in to dust themselves? Fill me in! Thanks!
