My plan for the week seems to be working well so far. Tonight he came to the gate when I called him. Gave him some carrots and some scratching. Got his halter on him, managed to get him into the stable for a handful of food. Then back to the field for more carrots and scratching. Hopefully this is all making me more interesting to him.
Didn't try to play any other games with except for asking him to back away from the gate when I opened it. He took a step back just from a phase 1 wiggle of my finger so was pretty pleased with that.
