They get no hay at all in the winter? That is odd, I know they make some complete feeds but no hay at all just seems wrong and expensive
I can see the point of dropping weight. I know mine have been fat and sassy all winter just standing at the hay bale. I think it helps for them to be a bit overweight when the temps are low. They take it back off once their back off on the pasture and have to walk for their food.
