I noticed Hannah's hair seemed to be sticking up and just looked weird. I got her on the milk stand and she's losing her hair. Quite abit to. If I run my hand over her back and sides hair just starts coming off. She was doing this the other day but I thought it was normal shedding and didn't think much of it. But now she has these bald spots and I took a closer look and could see tiny bugs moving. They were whitish/creamish colored. My questions. 1) Is this lice? 2) If it is, what do I treat her with? 3) Should I treat the whole herd, or just the goats that's been in the same barn? Thanks in advance! Here are some photos of her.
