Wow that is quite detailed thank you. I would suggest checking out the Australian exhibits at the Living Desert and Cinncinati zoo both show how to do a proper kangaroo walkthrough. Now my worry is with the emus and that is don't emmus attack people. They have terrifyingly sharp claws, are like living dinosoars, and have had documented cases of attacking people. So besides the walk through killer bird exhibit (I'm Joking) this area is really cool
It's been done surprisingly often. And even then, the emus will also be able to go to the inside area
