i am not sure how much you know about bees but you are wrong, and missed it by a lot.
Drones are the only fat ones in the hive and they either die after mating or get cast out when winter comes.
queen bee is hard working. all her life is dedicated to making more bees for the hive, and would not survive on her own.
The colony relies on each other for everything within one another individual bees (workers, drones, and queens) wouldn't be able to survive. The whole colony is also needed to reproduce. The colony of a bee is a well-oiled machine working together to survive.
If you would like to pick one bad thing in this than that would be swarming. But i doubt it Hive will ever become to big so it has to swarm.
