Lol! The place I used to board at fed round bales too. Horses loved to use it as a pee spot when it was closer to the end.
To the last 2 comments: that place I boarded at made really small round bales (the smallest I've ever seen). So for 5 horses (1 very old gelding, 1 baby, 2 yearlings, and 1 full grown horse) it took 3-4 days to finish it up.
