There's a book out called "Parrots of the Wild" that has a section on the ages of reproductive readiness for various parrot species.Honestly, I would wait a few years until your babies have at least gone through puberty.
I don't have the book in front of me at the moment but if I remember correctly parrots that are approximately the size of a green cheek conure or smaller are sexually mature and active by the next breeding season after hatching.
As for the larger birds (like macaws) it doesn't take years for them to become sexually mature in the biological sense. They are sexually mature much earlier but what happens is they are not "behaviorally" ready to breed. They form pair bonds early in life (post fledgling) and will spend years together, synchronizing their behavior, becomming skilled (at finding food, etc.), and will even "play house" (by claiming nest sites and going through the motions) only to abandon the effort.
It's amazing how so much of their lives is geared towards mate selection and reproduction, beginning with their first learned vocalizations in the nest.
