I've got him in a roundpen right now. He charges all humans and other animals and he is perhaps the most frightened animal I've ever met.
Currently, I've been using my friend's blind horse to pony this boy. Patrick (the blind one) is awesome at getting out of the way and he doesn't take crap from anyone. Whenever the horse rears or tries to get loose, Pat will push him in the directions he wants to go.
Over the past week, the horse has been going great with Pat, but he still charges me when I'm alone. I do no it will take time, but anyone have any ideas. He's on Bach Remedy oils that have been helping. He's a big one, about 17.2, stud, and that's all we know. Drugs don't work. Can't geld him yet.
