Well, big cage is already better than small cage. Keeping them as single birds is not optimal though. My point is though that keeping single parrots in cages which are too small makes them a lot easier and cheaper to keep. Less area to clean, less potential for destruction, and single birds engage more with their Humans. It's just not really a situation were they thrive. I won't go into why the scientific consensus is that parrots need conspecific companions. But it's not so much about being happy or bored, but more about meeting social needs and exhibiting the natural behaviors.
