Did a quick check on 17 hives today before our next cold spell hits tonight. It has been a mild winter and I know there is a lot of talk about bees using more stores when the weather is mild. Most of the hives I checked where either single deeps of 5 frame nucs. I figured these would be the ones that might need feeding. It also included a few 1 deep/1medium hives. I was pleasantly surprised with what I found. All 17 where not only alive, but loaded with bees and still had plenty of stores. It was too cold and windy to pull frames, but I could see plenty of capped honey from above. I know at times I take a lot of flack from those at Beemaster who are strong supporters of creating ventilation. But I still attempt to replicate what the feral colonies around here do. These hives are all polystyrene with no upper ventilation. Some have a 2" insulation shim, all have 2" insulation covers. They have a 3/8" x 3" bottom entrance. The hives where last opened in the beginning of October which gave the bees plenty of time to seal all cracks, which they did. None had any signs of moisture or dysentery. The first two where 5-frame nucs (actually two 2-frame queen mating nucs) that where moved into the 10-frame poly hives in September. The last was a full sized hive.
