Ben and the Sliding Roof Monsters

Poor Ben. The last few days he hasn't been at the fence to greet me when I drive in; the last couple he hesitated to come get his bucket of mash; today when I finally coaxed him to come get it, he ate about two-thirds, then went back to the far end of the paddock, and wouldn't come to me till I carried his bucket a good two-thirds of the way to the back.

Why?

Because there's still bits of snow sliding off the barn roof, and the poor thing is spooked! Monsters are sliding down to eat him up! Aaaiiieeeeee!

There's hardly any snow or ice left on the roof now; should all be gone by tomorrow; but who knows when the Benster (not the sharpest pencil in the box) will figure out it's safe?

This is where he should be:
