Mini filly kicking and other behaviour issues
I have a 2 year old mini filly with a kicking problem. She also seems to have some other issues as well.
A bit on her history. She was given to me about two months ago. The previous owner had bought her for her daughter as a foal when she was about 4 months old. As far as I know, she has spent the last 1.5 years tied to a stake in a backyard. No pasture. No barn either. They claimed she was put into their garage most nights but I have my doubts as it seems she has not been handled very much.
She was a little underfed and had some evidence of what looked like rain rot but its been cleared up and her coat is growing back. Her feet were decent but in need of a trim and now that's she's been here for a few months she is looking pretty good.
I have a mini stallion as well and they've warmed up to each other after a couple of weeks. At first she was not very nice to him. She would try to kick him through the fence for even coming near her, while at the same time throwing out all the signs of being in heat. After a few weeks of keeping them apart I've let them be together and she has finally calmed down with him, although sometimes she randomly kicks him for no reason. He's been taking it all in stride. He is still very well behaved and despite having a female in heat around there hasn't been any noticeable change in his behaviour.
I'm more concerned with how she has been behaving towards me. When she sees me she comes running. She likes being around me and will follow me everywhere. However, she does not like to be touched in any way. Even while grooming, she will shake her head, whinny, pull away and try to turn around so she can kick me. Sometimes she is OK with it but a minute later she is squealing and trying to line her legs up so she can kick me. Tonight as I was feeding her I passed by while bringing hay. I brushed against her side and she booted me square in the calf leaving me with a limp and a massive bruise. She knew I was there, I always make sure they know I'm around.
I need some advise on how to break her of this behaviour. At this point, working with her is starting to become dangerous as she lashes out for no reason that I can see. I won't let my wife go near her as she is just too unpredictable.
