Yeah, it's a little early for switching boxes in Wisco yet.
Fortunately we were near 60 here in south dakota the other day, rare for February. I took entrance reducers off right away in the morning hoping the hive would warm up sooner so the bees could get out en-masse longer, and maybe do some more house keeping easier. It worked, and I was pretty happy with the amount of hives surviving yet, (65 out of 70) and the amount of bees I saw.
I had put dry sugar on top of all my hives before winter and gave it a spray. They were two deeps and I left a medium super on most them as well. When I opened them up checking their stores the other day, I found several hives that had cleaned up the sugar, but still had frames full of capped honey. Many had been into the sugar to some degree and still had stored honey. I thought that it was kind of strange using the sugar when they still had good honey. I hadn't seen that before, Is this common?
