Maybe you could ask her if she wanted to add pellets while just with you because of all the energy his training requiring.
I wouldn't want to "add" them. Not only would that be way to much, it would also be a waste of money. Which I think she's doing now anyway on the oats:). Her thing is to be economical. Round bales cost less then square, but if you give thehorse free choice of a round bale they do waste alot. That's why she pitch forks it the horse. But even that makes me worry. Once you start tearing the bale apart and it gets rained on it molds in places. But she wants it ALL feed to him. She threw him some that I wouldn't have given him the other day.
Well it probably isn't for me to say, I'm not a boarding stable really. So it's her choice.
