Our horses have always been on pasture or have had free choice hay off a large round bale. This summer my horse situation is going to change and I'll be feeding my horse hay over the summer and I have no idea how much I should be feeding her come March. I'm fairly confident she will need little if any grain to supplement her diet. She is a pretty easy keeper and I do not do a lot of hard riding.
If anyone has any recommendation are personal experiences they could share it would be greatly appreciated.
