My 2 1/2 year old Nigerian Dwarf doe does this thing where she puts her head up, twists it all around, by her back and almost touches it.. or she'll just look up. It's really weird. She's not sick, she's done it ever since we got her. Her two kids now do it too. She doesn't have horns, neither do her kids. My other two goats don't do this, or I have never seen them do it. She also does it when I'm trying to drench her or something (in the past when she's been sick). Just curious. Thanks!
