Along with Colony Collapse Disorder and the Spring Dwindling, I had been expecting the hive to be less busy, or even dead... No way!
During an early inspection this hot Easter weekend (8am - the bees fairly sluggish), I found (a) bees building comb up the outside of the hive between the lifts and the boxes, (b) the super with foundation added last week almost completely built up into comb and (c) the brood and super, acting as a combined brood box, absolutely jammed with brood.
This was a full inspection, right down to brushing the hive floor, examining the brood comb and generally sorting out stuff. As far as I can tell, the main problem is that there is no problem. They are BUZZING!
Time to read up on what's happening. I have a sneaky feeling that they are about to swarm. Lots of drone cells, though I could not find any queen cells. To keep them busy, I have replaced one brood frame with a new blank frame of foundation.
Disappointingly little comedy Incompetence. I managed to gas myself with the smoker, with no effect on the bees, and several times had to traipse back to the shed having forgotten some key piece of equipment. No pictures this time, I forgot the camera.
