Your breeding, most likely not.
Your location and poor mating weather during the time the Queens needed to mate most likely yes.
Sometimes a queen will lay drones for a little while then get control and start laying fertilized eggs. Not the norm but occasionally happens.
Sometimes workers will start queen cells on unfertilized eggs (laying workers do this sometimes) confusing for us but they are trying to survive, usually not capped.

The hive with queen cells has like 4 beauties and they look like swarm cells at the bottom of the frames as opposed to emergency ones which i would have expected
