I also have a multi species parrot home and each parrot is their own. I did not bring any of my birds home to be a companion to another.
Do they like each other, who knows as they each do their own thing and with each parrot and me, its one on one. My parrots love their one on one time with me, my wife and son and not with each other.
They will put up with each other just to be around my wife, son and me.
