They'd have to drag that contraption quite a distance to get to new forage, I'd think. Maybe not so far to a "safer winter location". Regardless, it seems ridiculous, and I can't imagine it ends well. I'm guessing they "roll their own", if you get my drift. You can get by doing a lot of strange stuff with your parent's trust fund.
What was the purpose of that shelter? Cuz if they're trying to keep rain out.......that design is worthless. Looks like a lot of work for .......well, little in return. They shoulda worked the bees some before they went building shelter. Before I got my hives I built some stuff that is now useless. I've learned.
They need to put chicken wire around it and use that skid shed for a mobile chicken house. But it is way over built (heavy) for any practicle use that comes to mind. Or maybe they could pull it up on a hill and use it as a portable stage for pasture parties.
Nice idea, but, what are they going to skid it with, their truck? Will they put the hive(s) in the truck or leave them on the platform? Nice shed. Saw one like that on a peice of currency from 1780 something issued by the Continental Congress only it used posts and not skids.
