How can I help prevent a cribber from destroying the barn?
You have some options here for preventing cribbing in the barn. Many owners choose to use a hay net or other slow feeding device, as it takes much longer to eat a flake than if it's on the ground. Other owners choose a buddy, like goat or chicken, for their horse, and some choose turnout and a lot of it. (Although many cribbers will wrok on their habit despite the presence of food or pasture or buddies.)
At some point, there may also be a need to protect the surfaces of the barn and paddocks/fencing from teeth. Many folks use some form or spray or paste that is foul tasting. These are sticky and usually contain capsaicin, which will test positive at shows. It's up to you if you want to deal with the sticky, and be warned that some of the sprays will stain surfaces. Other folks swear by using plain old pure bar soap rubbed on all surfaces.
Soap tastes bad, it doesn't test at shows, it doesn't stain your horse or the surface you rub it on.
You can get sprays and goops for cribbing deterence!
This paste is super goopy and horrid tasting deterent.
An alternate to covering surfaces is to use a metal covering or PVC pipe that's cut lengthwise to cover all of the cribbing surfaces. It's a bit of labor, and some horses are unable to get a grip on that rounded edge. In pasture situations, electric fencing is a great option and very inexpensive to use.
ZAP! I love electric fencing. Keeps your fence and your horses safe!
One last tip - once you have your edges under control, many horses will use the water bucker or watering system to crib. Cover the bucket with a toilet seat and strap on. (Bailing twine use #4087). Some feed tubs can be fit with a wide lip what prevents your horse from grabbing on.
Like a frisbee, but not.
Many horses can't get a grip on the wide flat surface of a toilet seat or a bucket edge ring thing, and therefore can't crib. But they can still get to their bucket or waterer.
