I have just moved to a new yard and i am really worried about my gelding. At the previous yard he was stabled next to my mare and they could see each other through bars now they are in a barn together and can touch over a door. Since moving he will not be seperated from her, if I even tie her up just outside the barn so he can still see her he rears up and hooks his feet over the stable door. I have never had this problem with him at home she even used to walk past his old stable and out to the field and he was fine. The problem is I need to be with my daughter when she rides the mare but if I leave him I am scared what he will do so she is now suffering. When they are out in their field or even walking them to the field if another horse comes to the fence then he starts striking the ground and squealing. Any tips pleaseeeeeeeeeeeeeeeeee
