I recently purchased a 2 y/o paint mare. She seems good natured, but has been nipping at me often. When I first started feeding her I would pet her and she seemed ok with it. Now she slings her head at me if I get to close and once turned her rear to me as if she was going to attempt kicking. Needless to say, I don't stick around too close when she eats anymore as I know she feels her space is being invaded. She will walk up to me and allow me to pet her face, but eventually nips at me. I have to keep a close eye when walking near her in the pasture, once she began running towards me. I think she was just excited because I had come to feed her. I'm new at owning a horse, and would like to train her myself because I feel we will have as stronger relationship, but I need a lot of tips and advice. I have read much online already, but any advice you can offer will be greatly appreciated.
