The only reason i'm asking this is because it's beginning to cost me on a regular basis now to keep fixing fence.
My father in law has a quarter pony type mare, she's very food aggressive, is about half wild, and has absolutely no regard if your working with another horse or not, she's just an all around jerk. She's been on our farm now for almost 3 years, and just recently she got a fascination with chasing our cows, to the point where they're exhausted and go through the fence. I've tried throwing things at her, chasing her clear into the next pasture, catching her and tying her away for a while. And it seems nothing has sank in. No one fools with her on a regular basis, she's just a pasture pet, a really nasty one at that. I can't seem to find a way to get her to stop chasing the cows. I know they should be pastured separately but, all of our pastures are connected for the winter months, that way they have plenty of water sources to get to and shelter from the elements, and it makes it easier to feed everyone when there is more space. My grandmother in law said, that if she see the horse chasing the cows she's going to crack her with a whip (my thought is it'll make her run through the fence too with the cows). Would any one have any ideas to help? I'm stuck between a rock and a hard place. Thank you in advance!!!
I'm adding a pic so you have an idea of what she looks like...
