How long before a kiwi will lay another egg?

Kiwi birds usually lay only one egg per season & although the kiwi is roughly the size of a chicken, it lays eggs that are about six times the size of a chicken's egg. Further as Kiwis are not constrained by needing to be able to fly some Brown Kiwi females can carry and lay a single 450 g (16 oz) egg. Once a year, a kiwi lays one large egg that makes up about 15-20% of its body weight, then, 24 days later, lays another egg. The second egg is beginning to develop as soon as the first is laid. On rare occasions, a kiwi may lay a third egg. The kiwi can lay only one egg at a time, as the egg is huge.
