They all get along together and every once in a while I hear a squabble and it's usually two on a boing and one doesn't want to share... Remember all are fully flighted and they act just as does their wild cousins, they fly off to another area.
Finger pointing time and the squabble is over. If anyone does start something you can bet it's Mica (G2) as she wants to play all the time whereas the others want to rest.
I have the big Wrought Iron bird cage in a corner as I can protect foods and waters sitting on top, also when something is spilled that area is so easy to hose down. Nothing is in the cage as the door is one complete front and I have it turned towards the wall (not that they could ever open it, I barely can) so no accidents can happen...
