My Easter egger lost a tail feather this morning. I picked it up to and saw little tiny white bugs moving around.... I'm quite disgusted because I have been really careful at cleaning the coop and spraying with "Care free enzymes Poultry Protector" once a week. I've never seen any bugs on my flock. I have a hen brooding 10 eggs and I didn't want to disturb her so I haven't changed the bedding under her eggs, nor have I been able to clean the small chicken tractor by spraying it out with the hose like I usually do, for a couple of weeks now. I have heard of using Sevin Dust....is it the Sevin Garden Dust? Is this safe? I have also heard of using "Frontline" spray for ticks and fleas. I use in on my dog and cats.....Safe for Chickens? Where can I get DE food grade? What would be the safest and best way to treat my chickens and the unhatched eggs?
