Hi Funnybee
That’s really good if both boxes are being used! One or other of them, or even another hog might still be out and about. They don’t go to sleep, as such, it’s just that their metabolism slows right down during hibernation, so that they don’t need to eat. I would keep leaving food out until several days after the hogs have stopped eating it. Just in case another one turns up hoping for some food. It’s a good idea to leave water available all winter. Hogs sometimes come out of hibernation for short periods.
