Anyway, one day as I was taking care of my two boys (both geldings) and could see the dry-lot "pasture" they were kept on and the herd. They had two LARGE pens, one for geldings and the other for mares, while this one was the "co-ed" pasture. There were about 10 horses or so on 2-3 acres. As I was watching, a gelding that'd been there for a few weeks repeatedly mounted 2 mares. They were being very, erm, promiscuous, backing up and all ready for him, and he was just going back and forth. I don't know if he actually entered them, but he definitely was mounting them and this went on for quite a while and, of course, he was playing the alfa male with his herd of mares at the time as well.
I mentioned to some of the boarders to see what was happening, including the trainer there and another lady who are both close with the BO. Next time I saw the gelding's owner, I told him and he couldn't believe it. But there was only one black gelding in that pen, so I couldn't have been mistaken...
I wasn't sure if this was an "acceptable" thing since it was the first time I'd boarded my horse. Moreover, I didn't feel like people took me seriously on other things regarding my own horse's care (another reason why I left), so I may or may not have mentioned it directly to the BO. I figured the people who were there at the time and that I showed what was happening, given their relationship with the BO, would have brought it up if something should have been done.
My gut instinct is that there would be SO many issues with this - injury to the horses, infections, etc. Am I out of my mind, or is a gelding repeatedly mounting mares something that should have been dealt with?
