Should I be panicing?

[Pollybell]

12th May swarm from my one over wintered hive. Captured swarm rehoused in new hive and they are thriving. Squashed all but 2 QC in old hive - none capped
26th May capped QC in old hive - suspect not one of the two I left
30th May QC uncapped but cannot see queen
10th June still no sign of queen, eggs etc.
Is the queen in residence but not able to go on mating flight due to poor weather? Or should I be panicing and thinking of reintroducing a new queen somehow?

Can you obtain a frame with some young brood in it to use as a test frame?

I could take a frame from the rehoused swarm hive. I assume I add this and see if they produce QCs?
