Been there and done that! A big ouch!
Nasty QH mare, turned around on me because she simply did not want to move over, so she decided to give me a piece of her mind. Kicked me good in the upper thigh and she did not stop at one kick, she kept kicking, shoving and trying to get me pinned against the wall. She did not last long, told the owner to take the spoiled horse back. Then the horse died of founder about ten years later...and no one could ever train her. Neither did her daughter that wanted her in the first place wants nothing to do with this horse who acted like a goat. Nasty, nasty horse.
Another one was a Paso Fino stallion, who loves to bare his teeth at anyone and everyone. Had a hot wire lined in his stall as well! The owner told me to do things quickly dump the feed in the wall container, throw the hay on the far corner but he was ok when you want to take him out of the stall to clean but beware of his teeth. One day, I threw his feed in the wall container, he nailed me good in the shoulder, good thing I had a whip in my pocket and beat the living daylights out of him, I mean BEAT the tar out of him! Rage is what I felt that time and I was ok but very sore. That evening I went back to do the feeding again, he saw me, went to his corner like a quivering mass of horseflesh...he was scared sh**less of me! Only me! Anyone else, he would attack. When I left, he nailed everyone until he was gelded but his attitude was nasty still. Glad he died many years later. Good grief, some of his offsprings were nasty like he was. So I avoided those lines of his.
Get well fast and put ice pack on it.....you will be sore for a good while!
