I'm moving to BC in June, and i'm buying a new cage for the birds. Right now they're in three similar cages, but its WAYY too much to clean.

So to make things easier, I was thinking something like this:
not that exactly, but the basic idea of a smaller cage on one side, and a larger one on the other side. That way Indy can have a seperate cage from the girls. But I was wondering how big a cage has to be to house two poicephalus together.
Or, another idea was just to house them all together in one large cage like this:
But that means boys and girls would be living together- and I don't want anymore birdies.

What do you think?
