Since the day I got Major he has always been so passive. He has stayed in a pasture with my sisters horse. My sisters horse has always been the herd leader and Major seemed very content with that...never challenging him. A week ago my sister and I moved our geldings in with a couple of mares. The first day they ran Major around...bit him, kicked at him....you know...showing him who's boss. By the next day...Major was the herd leader!!!!!!! In charge of all 3 of the other horses!!!! I didnt think he had it in him!!!!!! Lol Now the pecking order is Major, mare #1, my sisters horse and then mare #2. I was so worried one of those mares where going to hurt him...he never fails to suprise me!!!!
