We recently moved our 2 year old mare to a different stable two months ago where she is in a paddock with an alpha mare and gelding. My girl Mabel is extremely sweet and shows no aggression. Jane the other mare is still constantly trying to keep her title of alpha even though Mabel shows no signs of challenging her. She backs up on me and is crazy when I feed in the mornings pinning her ears back and rear to me. The other day she cornered Mabel in the barn and just started kicking and didn't stop until I was able to get there. I'm worried she's going to hurt me or my horse and not sure how to handle the situation. There's not another paddock we could move her to either. Any advice would help!
