This project is for documenting observations with multiple animals of the same species at different stages of life. This can be one of many different situations. A few examples:

An adult bird feeding juveniles or with eggs
An adult insect with nymphs, or nymphs of different instars
Any animal that has already hatched from an egg where other eggs are still unhatched.

It's not required but if you know which life stages are present, add observation fields to assist in filtering.
