The horses split the herd on their own, one would go to the lower end and the other would stay closer to the barn, sometimes the herds would be about 10 feet apart, but if there were any issues, the herd leader of that particular horse or herd would handle it.
We had one like that, but both of my dominants were smallish old guys and this new one was a big dumb warmblood so he technically had the upper hand, funniest thing was one day Doodle (mine) got in a fight with Windy (boarder) and was holding his own but not winning, then Thunder (my other one) comes trotting around the corner and they both layed into him together, once Windy threw in the towel then Thunder went back to his herd...
That makes sense and is really cool. I guess I wasn't wording it the best though, I was wondering if they had like a big pasture with tons of room to split up or more like a corral/dry lot like some people use. I guess they could split up even in a small area if they wanted to though
And LOL that's hilarious! Were those the two that split up?
