Well, hopefully you get rid of those things! I am always afraid I am going to get mites, constantly checking for those things.Now I'm thinking it's mites. Ew. I sprayed my pullets with permethrin according to package directions. So much for being organic. But I found pics online that look like this. I will take any advice. I will do my very best to clean out the whole frigging coop tomorrow and spray everything down.
Poor Iris. Wish I'd seen this sooner. I look them over every day, but I somehow missed this ugliness. And my coop is pretty darn clean. I may just dip her, too. She's a hot mess.
And I've got my broody in there, too. She's just a sitting buffet for the %#=^*& things.
