I really appreciate all your input. I'm going to start first with just 2X senior feed as not to shock his system, and then add from there. The only thing about beet pulp...since I board my horse, is that somethng I could soak/perpare once a week and leave at the barn for them to feed? Or prepare as often as I ride? (i.e. I come out to the barn 3X a week...could I leave enough each time for them to feed). Or is it something that has to be done on the spot?
