My sheep like to come up to the fence and lick my hands but they seem to get a little carried away and try to get my hand in their mouth. Since they don't have top teeth, can they bite me? And if I keep my hand flat can they still get my skin?
Yeah these are the lambsAre these the lambs?
If so, normal.
Like puppies and human young, they use their mouths to explore and sooth toothaches.
It's not really a problem unless you let them use their back teeth, that'll split your skin and make you bleed.
They can scrape flat objects with their bottom teeth, yes.
