@skeggley, I typically have a hybrid, a full flow, and a half deep super on my hive. This year the blossom in my area was less than last year so over the weekend just gone I’ve removed the full flow and half deep supers but left the hybid on (last year I only packed the hive down e-April/early May). I made a god awful mess extracting the full flow super on-top of the front loader and then (last night) have put the full flow super on-top of the migratory lid for the bees to hopefully clean up over the next day or two before I freeze them (after taking EVERYTHING including drawers out) for two days and then pack them in a plastic tub for winter. I can likely let you know in a couple of days how well the bees cleaned them ready for storage.
Last year I didn’t do this last step (on top of the migratory lid for a day or two) and had a mess to clean when I went back to the frames in Spring…
