Two Birds in One Big cage

[svolk]

I would not house different species together. Even if they appear to get along at first, when one or both hits maturity it would likely be a different ballgame altogether. I, personally, wouldn't risk it.

And Wiggi, I wouldn't house budgies and tiels together either. Their personalities are too different, budgies are generally too hyper whereas tiels are much more laid back.

My cockatiel and my conure play together, and enjoy themselves. They also travel in the same cage, but share a mutual cage in the home would be a mistake. The grays play, they are a bonded pair, and they too travel in the same cage, but not in the home.
There will always be a dominate in any society, be it avian or human. Live sided by side, and things are cool, in the same 'house' and it's enviting trouble.
The teil and the grays are dusty, and live alongside the macaw and the conure very well.... but I also take the precaution of air cleaners.... it's those 'just in casw' things that can make the difference in health down the road.

if you cant aford another cage, and that one is big, have you thought about dividing that one for now till you can get another one?
