The joeys are pretty much in good hands with their parents if all circumstances are taken care of.
They take very good care of their young & generally don’t need any help from us humans in captivity.
When the joey reaches the age of about 8 weeks it should be ready to wean. At this time the joey is eating & drinking on its own & is ready to get to the bonding process of life with its new owner!
If you need to supplement milk for your joey wambaroo milk is very effective, & there are also a number of other milks you can water down to make a good replacer.
