It can be done; sorry, I do not know of a youtube on it. It is best to have a rather small zoo since you would need habitats within habitat for the other animals and 1. guests do not view one habitat from another habitat and 2. need it for the barrier gates to work. I assume you want a layout where the peafowls roam freely in your zoo but you also have some other habitats for other animals. Again, best for a tiny zoo as there is some setup that has to be done and I assume you are not talking about just having a walk through in a separate peafowl habitat.

A more simple way is to create a picnic area within a habitat full of shops and picnic tables. That could be a large place with a couple species or even a restaurant, or along a path that leads to different sections of ones zoo. creative use of the null barrier and scenery could even create a situation without walls giving the appearance of an open area.
