Research suggests ducklings communicate with each other from inside their eggs to help coordinate hatching, which may provide an evolutionary advantage.

Baby ducks actually send messages to each other from inside their eggs by clicking and tapping, helping them all hatch at the same time. This is pretty neat because it means they can all go to the water together as a group, making them less vulnerable to predators.
