I'm not sure if I'm in the right section of this forum for this post but it made the most sense to put it here.
I've had my mare now just about a full year. She just turned 3 and is a complete doll. Very quick to learn and sweet with just about anything.
Im very concerned though, she has started to become destructive in her corral, stall and even the arena when she is turned out. She pins her ears, spins quickly and bumps her rear end into the fence, panels walls or gates. Sometimes throws a full buck into it. It's so random you barely catch her until she's already done it. She's most the time alone when she does it. I'll be in the tack room or walking away. She recently did it while tied but was only able to swing halfway and then kick a pole, I was in the tack room still with in her site. She seems to do the most damage when I'm not even there.
She gets out and worked every other day at least. Her corral and stall is not by any means small. She has a jolly ball. She's fed with a slow feeder net, which takes her a good amount of time to 'graze'.
Is she lonely? Neurotic? She has been fecal tested for all detectable parasites. She's current on all necessary vaccines.
I've never had or even witnessed a horse like this. I'm in fear of it getting worse and causing real damage to herself.
Has anyone experienced this type of behavior???
