If she goes without hay you are inviting ulcers. Get some small mesh hay nets which make the hay last longer. She doesn't need supplements nor the oats at this time but more hay. Put the horses together and give both a net and hang them well apart. Your gelding will do better with a net also. Remember, with horses, the faster it goes in, the faster it goes through them. The body takes only what it needs from the supplements and often they just make expensive manure. One of the reasons horses get so fat with round bales is because they only move to get water. For two horses, my preference is to get two and set them as far apart as possible. The horses will eat from one then go check out the other, back and forth. Moving thro deep snow keeps them in shape. If you can get a few bales of oat straw, she can eat a flake per day, perhaps divided. No food value but it provides the long fiber the gut needs without putting on weight.
