Sorry, IDK why I thought you were talking about a mini LOL
RB's are great for easy keepers b.c they ARE designed to be fed at 1lb per day for the average 1,000lb horse.
My horses are on a low sugar/starch diet also. Not b/c they have problems, but b/c it is the healthiest option for them.
4yr old 850lb QH mare
1lb Buckeye GnW RB
4lbs Alfalfa pellets (weighed before soaking)
9yr old 1,000lb APHA mare
2lbs Alfalfa pellets
Both are on free choice grass hay via round bale, both stay out all the time.
I feed the alfalfa pellets for added calories. I was happy with the RB alone this past summer when they were on grass, but I wanted them both to gain a little weight for the winter and maintain that weight, so I added the alfalfa.
If your horses is that easy of a keeper, put her on 1lb of a quality RB and grass hay soaked for as long as you can if you are worried about the hay.
This diet is healthier overall, so please DO feed it to your other horse.
