Well she's done it again, except this time she's hurt someone else. We've put tons of time into this mare and she now stands tied relatively nicely and quietly with minimal pulling back. I had her tied at the very end of the barn to groom her after a work out. A girl comes riding her gelding (bareback) in the barn up and down the isle. I warned her that my girl kicks, and not to come behind my mare. She rides back down the isle and I walked into the tack room (converted stall), and as I walk out she is behing my mare and Veg kicked her gelding right in the ribs and she fell off. She jumped up and caught her gelding that was bleeding (he got kicked right behind the girth area in the ribs) and I just checked that she was alright and her gelding wasn't too terribly injured. She called her dad out who let me know that I would be getting stuck with vet bill for her horse, and that my mare should be shot. Vets coming out today, it looks like she only broke the skin and he is very bruised. My question is, am I really responsible for this girls vet bill. In my opinion, she got her horse kicked as she was given a warning and my horse was tied out of the way.
