ELI5: How is the queen bee chosen?
gpt
When a hive doesn't have a queen (because she's died or flown away), or when some other conditions are met, the workers will move a few eggs into special extra-large cells and supply the grubs the hatch with special food called royal jelly, so that they grow to be queens.

The first of the queens to emerge from her cell immediately goes around and kills her unhatched competitors, leaving no competitors.
