In the fall I put a super back on one of my hives after extracting so the bees could clean up the frames. After a few days I checked again & they were still really busy cleaning so I left it. Time got away from me& I left it on all winter. I know bad beekeeping! I went out today & it's about 48 degrees & there are tons of bees in that hive & of course they don't want to get out of the super. What should I do? That hive is really aggressive so it's not too fun to work with.
