I'm new to this forum, but have kept bees for several years, but hit a new problem. I went out to what had been my strongest hive (out of 3) & found it empty. There were about 4 frames with capped cells, some brood, and plentiful eggs. Also some pollen & honey. but less than 50 bees & no sign of a queen. The capped cells looked to be workers, not drones. I hadn't opened the hive for a couple of weeks, or done any painting, spraying, etc this year. Also the other hives on the stand seem to be doing fine. These bees had been gathered from a wall & had been in the hive for three months. The only thing I can think of is that they got too hot (it only got to 95), & decided to move on, but I've never had them abandon brood & eggs. Anyone have any ideas?
