Ok, I had a hive to swarm, (lost the swarm) found several queen cells so I placed one in a nuc box with three frames of bees and larva. A month goes by, in the brood box the brood all hatched and cells empty, and queen cell empty , but no sign of her anywhere, I checked several times over the next three weeks but still no queen to be found... TODAY I found larva! (But it started to rain so I didn't get to look further) Does this mean the queen maybe was out on her mating time when I checked or maybe I simply missed her? OR could the larva be the result of workers desperately trying to keep things going without a queen? I have heard they will lay eggs. I'll check again this weekend, hopefully.
