We were so ashamed.
I have since confirmed the presence of mites (or are they poultry lice?) with my own eyes, and they are more horrifying than I had imagined. I spent much of today chasing chickens around the yard and dusting their vents with toxic white powder. The good news: no longer a mite to be seen. The grotesque bloodsucking arachnids that were making our chickens tired, feeble, and ill have been vanquished. A follow-up dusting in a week will take care of the babies. The bad news is, I'm going to get cancer from inhaling Permectrin and I don't think I can say our eggs are organic anymore.
I'm all itchy. Farming is gross.
