Hi all- looking for some help as I am very worried about one of my top bar hives. I did a thorough inspection on Saturday (48 hours) ago, and was shocked to see a large population of somewhat grumpy, purposeless bees, with virtually no honey stores present. We have large meadows, trees, etc - earlier this spring the hive was thriving and had lots of brood and capped honey - now all gone. I don't know if their stores were robbed, or consumed, but either way, this colony is in trouble. I believe them to be queen-less, and will have a new queen on hand to re-queen the hive tomorrow (Tuesday). The bees do not appear to be foraging; there is still some capped brood to hatch, but no sign of eggs or larvae. The workers just seem to be hanging out in the hive, with lots of empty comb and not much work being done. I have feeders available with 1:1 sugar syrup they can easily access, but not even a sign of capped syrup. Any suggestions for what might be wrong, and how to try to save this colony would be most appreciated.
