This is a theoretical situation as of yet. I don't own any horses at the moment, but I do teach at a facility, and the horses are stalled, fed twice a day. I would be boarding at a different facility, actually, and he'd have a larger stall with an attached paddock to himself. I was just curious because my father-in-law goes on and on about pellets, and it seemed off to me. At the boarding facility I'm planning on boarding at once I do find a suitable lesson horse, there's a personal tack and feed room attached to your horses shelter, with a hole between the two to throw hay. After this conversation I'm thinking I would attach a hay net around that hole and push hay into the bag through the hole. There is a manger below to catch any stray hay. It's amazing how much I have leared on this forum in the last couple of months that I was never taught. Thank you everyone for sharing your knowledge.
