Sorry about the miss communication, I should have given better details. They do get hay in the winter, they get it in their stall before they are turned out. They were getting about 2-3 flakes in the morning and 2-3 flakes in the evening when they were brought in during the winter. However, they are out for about 10-11 hours with no hay in the pastures. She says that she does not want the horses to fight over the hay. It seems like every farm I pass around here, the horses have hay out with them when the ground is covered with snow. Maybe those horses do not get hay in their stalls.
I would say that during the winter, the horses are worked less frequently than in the spring, summer and fall. And when they are worked in the winter, it is not very hard. I am just real suprised at how thin my horses are. I have seen my TB mare drop weight around this time last year and the year before, so I kind of expected it from her, but not from my QH. I am just worried that this is not healthy for them. I know it is not healthy for them to be overweight either, but they were a good healthy weight during the winter and now she has cut them back to what looked like about a flake of hay and about 3 - 4 cups of carb guard twice daily so that they drop weight before they are turned out on grass. Let me know what you think. My horses are not the only ones who are skinny. There is another TB mare that is skinny as well.
