Odfrank, have you been putting brood frames above the excluder with eggs or young larvae?

I have seen queen cells started, but usually when there is at least a super in-between or they are not used to an excluder. The sudden drop in queen pheromone to the isolated nurse bees, even just for a few hours, can be enough for emergency queen cells to be started. Once queen cells are started they are often finished.

Otherwise, as Roland said, it sounds like they have swarmed.
