I don't know what to do next! Whenever she does it I yell at her, chase her away from the fence, throw a rock at the fence (not at the horse, don't worry!!) to make a sound to scare her off...She always leaves but never fails to come back to suck more air out of the wood.
Today I soaped up the fence ALL the way around her paddock, took me a while. Then I turn back around in 5 minutes and she's chewing at it again. I realized that when she's cribbing she's using only her teeth...not her tongue or anything so I guess soaping it wouldn't make a difference if she isn't tasting it but I had heard it'd work.
What do you guys do for this??? Please Please Please reply!
