OK, I hade a hive swarm 2 weeks ago and posted some pictures. There were 6 or 8 queen cells on different frames. It's been two weeks and we went in again today. The queen cells were all open at the bottoms. We did not find a queen and did not see any eggs. When should we start seeing eggs. But this was something I noticed. While we were looking over the frames, the bees were on top of the frames in the brood box and lined up around the top and they were fanning big time. Just like you see when you capture a swarm and have the queen in the box. I really have never noticed the hives doing this on normal inspections. I am hoping that is a sign that see is in the hive.
