I only have one hive, but my beekeeping friend that got me started, has 8 hives. Last year he overwintered 10 hives and 8 of them survived. We went to check on their honey stores today and to see how they were doing. Much to our dismay, of the 9 hives between us, only 3 have living bees in them still. My hive is doing extremely well, and one of his is looking pretty good. The only other one of his that has life, really only has a handful of bees and I expect it won't last long.
Any ideas as to why they did so poorl this year? The odd thing is that 4 or 5 of the 7 dead hives have hardly any dead bees in them at all, as if they all left. But a month ago they were all doing okay. They all seem to have plenty of honey in them as well. Any ideas???
Collect some samples and send them into Beltsville Labs. Sounds like CCD if there was still stores left.
