How do you tell how old a baby wallaby?

To determine the age of a baby wallaby, also known as a joey, you can observe its size and development stage. Joeys typically stay in their mother's pouch for several months, emerging gradually as they grow. If the joey is still in the pouch and very small, it could be just a few weeks old, while those that are partially or fully out of the pouch are usually several months old. Additionally, examining their fur development and ability to hop can provide further clues about their age.
