I put the bees and caged queens in two new hives last Saturday with an empty super on top with a gallon can of sugar water for feed. Weather was cool this week (20's - 60's) but they were out and about a bit. This morning there are only a few dead bees outside the hives. I opened the hives up and verified that the queens were released and there's lots of activity. Some comb building has started. Should I be looking for evidence of sealed comb yet?
