Loving the herd life
I have a 28 year old gelding and a 30 year old TW mare. Both are rolly-polly fat and slick. I feed them a 14% all purpose pellet and have for years. I used to drive 50 miles one way to get it, now it is only 20 miles. It has a sugar beet base and they love it. You might get beet shreds and moisten with some warm water to make it easier to chew. It doesn't have to soak for very long.
That's basically what I feed too, 14% cattle ration (the horse ration from the same company is pretty equivocal on the bag) and mine are literally obese right now, in the dead cold of winter.
