I was hoping someone could help me with my bee math homework and let me know if I should be concerned. My hive swarmed around July 24. I did not get in there to inspect until August 16 (23 days). The hive is one deep and three shallows. I found two raggedy remains of queen cells, on the lower edges of the frames. The top two shallows were packed with honey, mostly capped. The lowest shallow had some honey and uncapped nectar. There did not seem to be much pollen. The deep had some nectar and a lot of empty space. At first I was alarmed because there was no brood, but there were a LOT of bees in every box, and they were gentle and calm. Given the time of the swarm (+/1 a day), is it conceivable that all the existing brood has hatched, and the new queen has not started laying yet? Keep in mind also that I did not have my glasses, so if there were eggs, I may not have seen them. There was definitely no larvae or capped brood. Any cause for concern? Estimate of approximate date I could check back and look for larvae? I did add a fourth shallow since they were starting to build comb in the inner cover hole.
