My friend and fellow newbie, called yesterday and said that when he went to feed his weak hive, he found that both hives were dead. He said that the dead bees were still filling both hives. We checked these about three weeks ago during some warm weather. The strong box had a full medium of capped honey, and the weaker hive had six frames of capped honey in the upper deep. There is still plenty of honey in both boxes. Any ideas or things that we can look for to explain this. Thanks for any help.
