But I knew him being out 24/7 was going to make rations a bit more challenging. The place I'm keeping him said they will be putting round bales out in the next month once they pull the kids off the pasture for the winter, so hopefully he packs on some pounds this winter.
Okay, now that we know a little bit more....
Definitely alfalfa or alfalfa-grass pellets, soaked. Best would be two meals.
That alone should help a bit. He's probably dealing with ulcers too, considering his previous living situation. The roundbale will help with that, if he gets a chance to eat from it. I'd be watching closely. If he keeps getting chased off the best roundbale won't help. I'd get some slowfeeder nets in that case, fill them from the bale and hang them on fence posts, a little spread out so it's too much trouble to chase him off.
Having roughage available at all times is the most important thing in getting him up to weight, not get cold and take care of eventual ulcers.
