I understand your frustration, Amy. I think POSSIBLY some of the issue has to do with the fact that the horses aren't led in daily, rather the gate is open and they charge each other in a crazy free-for-all to the barn at the end of the day. I also know that your boy isn't the only one guilty of this behavior, so don't get too down on yourself. I think that he has some jealousy issues, to be honest. If you remember the incident awhile back where I was out in the pasture with Dallas and your boy got pissed, ran up, and kicked me. I honestly believe he was jealous of the fact that a horse lower on the pecking order was getting the attention. Maye it's time for the horses to be taken in-hand to and from the pasture, and see if that improves everyone's manners at the gate, not just your boy. Hope things get better soon!!
