What is the best way to treat them?I don't see mites at all...just the almost clear little, what I am assuming are lice? I'm only seeing them on a few ( like 4 out of my 36 hens) -- Should I treat everyone preventatively?? I've read a lot about DE too..is that the best route to go?? What works best/quickest/etc... I wonder too, when you are treating the hens (I've read Severin--not sure what I should use??) do you just toss their eggs?? We've never had these before, grosses me out...my coop is clean, but near trees, wonder if the local wildlife birds have "shared"?? I'm going to clean it out again today...I've read orange oil or something like that mixed with a bit of vinegar to spray around?? Help!!-- Any suggestions how to keep this to just my four birds and how to treat the coop and everything else -- would be greatly appreciated!!
