We have been having CRAZY weather lately, going from 80 degrees to 40 degrees within the span of a couple days. So, since that crazy weather change happened, I noticed first one bald spot (on the bridge of the nose of one doe) and then another (different doe, near the nostril). I found one more this morning (on the top of the head, a third doe). The girls are definitely feeling itchy, and scratching themselves with their teeth... they're also eating more food than they usually do (but that could be due to the cold weather as well). So, this morning, I went NUTS with the DE, dusted each doe individually (and rubbed it into the fur) and sprinkled it all around their shelter. Is there anything else I should be doing? Also, any idea what kind of lice these might be? I've had itchy girls before (and dusted then) but never these bald patches. The bald patches are greyish in color, hairless (of course ) and just look vaguely scabby. I'm praying it's just the weather change and the DE will fix everything up, but I did some research this morning and started reading all kinds of horror stories about anemic does... and these girls were all bred in the last month or two so I definitely don't want that happening!
