What I would do is nix the 12% pellets from their diet. You're not feeding them enough of it to give them any real vit/min or nutrition. Instead, mix with your oats a good vitamin supplement like Grand Vite, SmarkPak's Smart Vite Maintenence Grass (comes in pelleted or powdered form), or horsetech.com's High Point Grass. All three of these are complete vit/min supplements with added amino acids. Your horses will be getting all of the vitamins and minerals they need.
You can easily adjust the amount of oats they get, add a fat supplement, and/or add alfalfa pellets should you decide they needs more weight/condition, without worrying about their vitamins. If your little one is too fat, you can easier reduce the oats down and still be confident that she's getting all the nutrition she needs.
I have mine on a similar diet, except they get added flax meal and alfalfa pellets, but our horses are ridden 3-6 times a week in lessons and some trail rides. The horses ridden the least get no oats, just a little alfalfa (1 qt), and just a little flax (1/4 cup). The horses in heavy work get 2 qts of plain whole oats, 1.5-3 qts of alfalfa pellets, and 1/2 to 1 cup of flax meal.
Having this kind of diet is much healthier than loads of feed or grain and it's much easier to adjust as needed. Mine all get less food during the summer when grazing is good.
