When I use to do roundbales and had one BIG QH/Appy mare out on it, she would take about 3 weeks to eat it. These were 600lb bales. Funny to watch before I bought a bale feeder for her because when she ate the center out and was almost through to the other side, she would stick her head in one side and out the other. The roundness being kept because the waste hay was on her back.
You know how to make a miniature horse even smaller? Leave them in the dryer a little longer!
