How many eggs can a kiwi bird have?

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.
