Why so worked up about cribbing? I have a cribber and to me, it's just annoying. There's nothing you can do to stop it, and trust me, I've tried EVERYTHING short of surgery. Certain horses are genetically hard-wired to crib, and they don't pick it up from watching other horses or whatnot. If they don't have the predisposition to do it, they won't, and if they do, they will always have that habbit.
My horse has destroyed three corner feeders so we had to get him a grain dish for the ground. He also broke his water bucket.
But when I was in his stall with him I used to pop him under the tummy with the heel of my palm every time he cribbed (just hard enough to make it uncomfortable) and now he won't crib when I'm watching him. But that's as good as it's ever going to get. Lol
