We recently got a puppy. When we got her she had a few fleas, as do our cats. But today, after the dog was in the barn and under the porch where the chickens were escaping from the heat, the dog came out literally crawling with fleas. You could see them all over her, on top of her white fur and down in it. Obviously we will treat her, but I wonder if it's safe to treat the area under the porch and the barn with sevin dust with the chickens there? They're scratching & digging & dusting themselves in both places. I don't want to poison the chickens, though! Help, anybody?
