Maybe it won't be too bad. My Percheron stud came home as a yearling. He was turned out to pasture with all of our other horses and I did not mess with him at all until I started riding him. He came broke to lead and nothing else. Just this last time I went home, I caught him and my Dad saddled him (I am not tall or strong enough). Within about 20 minutes of leaving the pasture, I was trotting circles in a pen on him. I can't wait for your girl to grow up. I would love to see some summer pix of her all slicked off.
