I did see a few smaller looking kangaroos when I last visited - however since they were off at the far back of the habitat, I assumed they were just some of the wallabies.
Good to know Melbourne have already had considerable breeding success with this group; the group consists of five adult females, so hopefully there's a few more joeys yet to emerge.
The update said there was a ‘few new joeys’, so that means there’s at least one more (in addition to Zac and Bree).
Any female with young venturing out the pouch can already have her next joey at the jellybean stage, so hopefully they’ll be more emerging over the summer.
