Two to three eggs are laid and incubation lasts between 25–27 days. Both parents incubate the eggs and raise the nestlings. The nestling period is between 9 and 12 weeks, and the young fledglings remain with their parents for a number of months after fledging. [5] Sulphur-crested cockatoos have a range of visually observable expressions.
The breeding season of this cockatoo is mainly from September to January. The birds build their nests in a tree hollow or rock crevice. The female lays 2–3 white oval eggs, which hatch after a period of 30 days. Both parents incubate the eggs and in turn provide for the chicks. The young fledge after about 75 days. [citation needed]

The chicks leave the nest about 84 ...
