Hi, here is pics of our outdoor cage
https://www.chameleonforums.com/blogs/dez/663-outdoor-enclosure.html
At times I keep juvi females in this enclosure.. At the moment I have about 5 young veiled girls in there that are for sale.
They do not stay in this cage their whole lives. Once they get to a point they have eggs they are moved to a separate cage so I can keep an eye on them with egg laying.
Even tho chameleons raised together get along better there are still risks. They will shoot food out of each others mouths or try to shoot at the others eye. They may fight when one steps on the other one.
Injures can easily happen and DO happen.
Ideally I like to use the cage for a mating pair or 1.2 group. But when I have many babies and need room I will put several females in the cage since it is large enough to accommodate them
Housing 2 females in a 2x2x4 cage does not work. I have tried this before when I was in a pinch for space and one female would always develop signs of an RI that would go away once she was separated.... I can only assume it was a stress related illness.
I also would not house two together that where not raised together
