Today’s the day I removed all the feeders from my hives.
I placed a hive top feeder over a rim on one of my hives about a month ago. I removed the feeder today and found burr comb built up over the top bars, the bees filling in the space I created with the rim.My best guess is the bees ran out of room for the syrup, so they began building comb above the top bars so they could fill it with syrup.
I had two other hives set up with hive top feeders in the same way, and I didn’t find any burr comb in either of those, probably because they still had empty comb beneath the top bars. But it just goes to show you, if you give the bees the extra space, they’ll eventually fill it.
I’m not worried about these bees starving over the winter. Hopefully they didn’t fill every cell with syrup, though. As much as I don’t want them to starve during the winter, they still need empty cells in the cluster to hold heat and keep them warm. It’s another one of those beekeeping balancing acts (an apt description for everything in beekeeping). You want to feed them, but you don’t want to feed them too much. Oy yoy yoy…
