Oops, try it again. Yes that is flashing their feet or heels. It looked closer than it was. I was outside of the pen and he was no where near me. Otherwise, if I had been near and he did that, he'd be dog food.
Since he did have so much energy I did go in, strip the halter off of him and work him a bit. The girls are in season so he's feeling a bit frisky anyway.
