I purchased a former race horse who loves to chew her stall when she is bored. She is outside for most of the day but in the barn from 5:30 at night to 830 in the morning. Times do vary but for the most part she is outside. I have sought the advise of numerous sources and am not convinced it is cribbing but rather boredom. She is on a recommend food with fibre. Yesterday I put out some free-feed minerals for her stall and then liberally applied vaseline with cayenne pepper in it. I even tasted it just to make sure it packed a punch. It did. This morning when she was fed and let out, we discovered that she now has vaseline, etc on her coat. Is this going to be a daily event or is she eventually going to clue in?
