I caught a swarm 2 weeks ago. When I got there about 4 cups of dead bees about 2 foot away from the swarm. Thinking pesticide I picked up a handful and smelled. No chemical smell, they were just wet and dead. The homowner said he'd sprayed them with water the night before he called me not knowing what they were. Crud, I forgot to ask about that... Nonetheless, I had a frame of eggs and wet brood in there to anchor the swarm. By coincidence if the queen was killed they'd let me know by making queen cells out of some of the larva. Even with all of the dead bees the hive was large and acting like there was a queen.
Fast forward 2 weeks, I checked the 5-frame nuc yesterday and they appeared (sound and actions) that they have a queen in there but there are no eggs. All the wet larva are now capped and there are no queen cells (fresh or torn down). I stole a frame of eggs from another swarm that's going gangbusters to give them something to do in case the queen is gone or hasn't started laying yet.
If the queen from this swarm was a virgin shouldn't she be laying by now?
