We had a horrible little mini gelding here for a bit- I am pretty sure he was proud cut. Of course with 2 mares cycling this spring he was horndogging it and was HORRIBLE. I had to keep him with my goats until he started attacking the goats. Put him with the cows, he finally escaped and harassed the mares until they kicked the stuffing out of him. My big mares had hoof prints on their butts because is was attempting to mount them. Thank goddess he wasn't hurt, but he could have been. I was able to find a home for the Horrid Little Pony and they have him on medication to reduce his testosterone, and is now a driving pony and doing good. It was not an experience I want to have again.
Spent a whole hour today laying in a pasture, waiting for a sparkling vampire to show up. Alas, I woke up and looked over, only to find a mound of horse crap. Sigh.
