I could not find the queen and did not see any eggs and only a couple larvae.
Difficult to say what have happened? If there is no queen there should be queen cells.
This weekend I had 2 case in my hive. In both there were queen cells.
1) I destroy all queens cells a week ago. Now I looked and I saw the queen. I noticed that they had brood any more and no new queen cells. I killed the queen and gived another. Queen was very good to make brood and did it become sick or something? It is angry hive and I decided to kill queen at once.
2) A big hive and I thought that swarm had tried to go and returned. I remembered taht queens wing was clipped.
This weekend I hear PIIP PIIP sound and I met a queen. I made a nuc and next day it layed eggs! I did not even noticed that it was old queen.
There was allready finished queens in cells and I made more nucs.
