I recently got a cribber into my yard. I promptly put him next to my own horse, who would become so incensed by the revolting "gulping" noise coming from the stable next to him that he'd fly at the cribber over the half-wall, teeth bared. Worked a treat.
The horse has now settled down beautifully, put on weight and his cribbing is limited to feed times. He consumes more hay than any other horse in the yard, and his windsucking muscles have almost gone away.
Cribbing is not contagious, but it is annoying. I have very open stables, they can all see each other at all times. Nobody else crib-bites.
