Well something interesting happened today. My (slightly crazy these days) grandpa let the two geldings into the pasture next to the stud. I went down this evening to feed and couldn't find the geldings. When I finally did I have to say I was surprised to find them next to Chorro. BUT there was no fighting. He didn't seem to care much about them. There were mares in sight but on the opposite side of the stud pasture. So I guess he wasn't to worried because he was between the geldings and the mares. However, it doesn't look like he's aggressive or a fighter.
Testosterone high or low I'll be keeping a close eye on him. The last thing I want is injured horses. I'll update with how things go after the big snip in a couple of weeks.
