I've trained my highly food driven mare to stand and only eat when I give her a cue. It's amazing what setting that boundary does. My friend was kicked very badly by one of her horses during feeding time because of this lack of boundary. One gelding kicked at another, and she was in the way. Horses are going to horse, and when feeding in a herd, fights are inevitable. Get to an understanding with your horses and claim space. Lovely video as always.
