Well, today was finally warm and sunny, so I took a peek in the hives. Not much fun. The one I thought was dead, was indeed. But now I want to figure out what happened. The (dead) bees were all in a cluster in the 2nd deep from the bottom, spanning about 5 frames. Most of the bees were on top of the comb and covered with mold. (If it hasn't been snowing here, it's been raining, and this is my first chance to get in here.) Th odd thing is that the cluster was on one end of the frames, and the other half of the frame was full of honey. The honey looked to be mostly crystallized, though. Some of the bees had their heads in the cells. In one area I saw what could have been brood. (?) Impossible to tell what was under the mold. The supers above had some honey, widely scattered and probably crystallized. There were a few streaks of poop inside the hive, but not a lot. The bottom hive body was completely empty, and one frame had an open queen cell in the middle of the frame. The last time this hive showed activity was on a sunny but cold day, when they were flying out and taking headers into the snow. Can anyone give me any ideas as to what likely happened here?
