One of my hives is getting tall enough - 4 med supers tall, and they were all hanging out at the entrance yesterday at about 4:30 and seemed very populous. Thinking it was too late to take the hive apart and do a split and we were tired from fencebuilding, I added another medium super. Today, I went in to do a split, and did not at first see the broodnest. I finally saw a frame with a little drone brood, a little worker brood, about 1/3 of a frame of larvae, and a few eggs, one or two of which did not seem to be placed correctly in the cell (but my eyes are not what they used to be either, that could have been my imagination) And I did see the Queen. Of course, there were no Queen cells.
The only thing I could come up with is that they had JUST superceded their Queen, and the new Queen was just getting the hang of things.
I just put everything back together again and did not do any splits.
Thoughts on this???
