We keep our horses at a friend's farm and we have for many years. They share a 13 acre field and four stall barn with one other horse, who also belongs to a friend of the owner. (The owner has 17, so 3 more is hardly a burden...and we pay board.)
The pasture opens directly into a small paddock that contains the barn. My problem comes when I'm trying to get one or both of our horses out of the pasture. Our OTTB is the boss horse. He's always first in line so getting him in is no problem. My horse is the bottom...so the other horse is always directly in front of him. AND WON'T MOVE. He wants to come too. Now, normally, I'd just push him away...but this horse has been known to swerve around and kick out... The gate is set into a corner, so there's only one way to move him. I KNOW what I'd do if he were mine, but he isn't. My horse is reluctant to walk past him.... or get near him.
We face the same problem in reverse when we put our horses out. He's right there at the gate and I don't trust him as far as I could throw him. We have NEVER encouraged this horse with treats, scratches, or anything else. We hardly ever see the other owner as we have different schedules and she has another horse whe spends more time with.
What to do? He WILL be in this pasture with ours. Moving him isn't an option. This isn't a major problem but it is an annoyance. I've never been kicked and I want to keep it that way.
