They don’t know for sure, but it appears to be a genetic predisposition, not for cribbing itself, but for nervous/habitual behavior that can manifest itself as cribbing. A bit like alcoholism/drug abuse in humans. I have a cribber (that Pinkdiamond used to pony at TTC) who had never been anywhere near a cribber (I had never owned one, and I didn’t have horses along my property line) that figured it out herself. It took her about 4 months to go from setting her teeth, to pulling and then one day she sucked air. Her dam didn’t crib but her sire did (who she obviously never met). She now raises all of my foals, and none of them have ever picked it up. None of my broodmares crib and I haven’t bred to cribbing sires.[/QUOTE]
VERY interesting. My Devil His Due baby, as I mentioned, does not crib, BUT he did start doing a head jerk/nose twitch thing a while back when we were in a boarding situation that was very stressful for him. It pretty much completely subsided when we moved (within a week of moving). It resurfaces briefly now and then if something exciting or upsetting happens.
