Each pair should have their own cage. The size also depends on where the babies will wean. Are you going to pull them and hand feed and so putting the babies in their own cage? Or will the babies be with their parents? Depending on these factors the size of the cages will differ.
I don't know why you want to breed them so badly. I don't even want mine to breed anymore, I didn't want them to in the first place. They used to hate each other but somehow everything changed when I had them all in the aviary....I am forced to remove the mother into solitary....You also run the risk with the mother with egg binding issue. But that happens sometimes regardless if your breeding or not. I am lucky that I was able to find good homes for mine and I talk to those new owners about the egg binding risk IF they get a female. They all have my phone number to contact me just in case of emergency. I teach them to clip their nails and wing clipping. And I also made them promise me IF they were to not wanting to have them anymore to contact me first and I will take them back.
