I’m pretty certain one of my hens has lice...last weekend I cleaned out all the bedding and nesting boxes, sprayed with water/white vinegar, put DE everywhere, and dusted the hen and the other three who live in her coop/run with DE. I read that I should be repeating this process once a week for three weeks...I’ve been checking her everyday since and she hasn’t had any more of what I suspect are lice...so I went out there to do the process all over again and she has the little bugs around her vent and butt area again. None of the other hens do. Should I bathe her? Or maybe do the cleaning/dusting process earlier than every week? Any suggestions would be helpful thank you!
