How do earthworms multiply?
They can perform both male and female functions and mate every 7 to 10 days. The mating process takes around 24 hours.

How do worms make babies?
Worms don’t lay eggs, they produce cocoons which contain multiple fertilized eggs. Earthworms are hermaphroditic, having both male and female reproductive organs.
