I guess I am just blessed! I found lice on my girls 5 weeks ago. I cleaned the coop, sprayed all the wood and cracks with liquid sevin at day 1, 7 and 14. I also dusted them and the nesting boxes and coop with sevin on those days. Tonight when I checked, they STILL have eggs on their feathers. I do not have access to DE. Any advice? I have 40 birds...do I really need to give them all a bath?
