My husband and I split 2 hives 4 weeks ago and moved the old hives to a location about 2 miles away. The new hives (left at home) are doing great. The old hives that we made the splits from - 1 is doing great but the other hive the bees are gone with the exception of a very small cluster. There is no queen or eggs left!! Anyone care to tell me what may have happened? Could they have swarmed? If we had mistakenly taken the queen out during the split, wouldn't they have made a new one.
