I got back from the vet and they found nothing wrong with her. I also spoke to the original owner and her sire rolls his head. She also has other goats that roll their head like that too. The vet also said that was normal. So I worried for nothing.
one of my gals did that when she was mad or frustrated. ..and the 4H kids told me it was b/c she was dehorned and was trying to scratch. my other gal does it when her heat is coming on
