A few hours ago, I noticed one of my five sheep is losing wool around her eyes. There are also some patches further back toward her ears. I washed her eyes with warm water to try to better identify what is going on. The skin is very flaky (chunks came off as I wiped), but also oily/moist, and seems to be somewhat tender (although I'd be skittish with someone holding me and wiping my eyes too...) None of the others shows any signs of the trouble.
I have spent the better part of this afternoon making calls, looking in books, searching online, sending e-mails, etc., to try to get to the bottom of the trouble. If anyone has experienced this and can diagnose it for me, I would appreciate the input. An added bonus would be a non-pharmaceutical way to treat it. I have diatomaceous earth if it might be lice, mites, etc., although I'm hesitant to use it so close to her eyes. I have GOOT if it requires an antibiotic solution.
I am concerned about the others catching it, but separating her from the others would be difficult, and traumatic for her. If it's necessary, I'll figure a way, but I expect I won't get much sleep - that's what happened in the past with a lonely ewe-lamb.
Thanks for any help people might be able to offer...
