Jstevens usually if a horse is bad at birth it is because of genetics. I have worked cows, rode cutters, roped for money, started colts, rode a few saddle broncs, made a few bridle horses, showed working cow horses and I have seen damn few colts that were complete garbage from the getgo. I have cut the heads off a few( chickened) when you could sill do that. Hell even made pepper sticks out of a mule, lol was pretty good. So there is a use for every horse or mule, even the bad ones. They make good bear bait where legal.
