The flightless kiwi is part of the family that includes ostriches and emus, despite the fact that it's only the size of a chicken. The kiwi has the largest egg to body size ratio of any bird — it lays an egg that is roughly 6 times the size of a chicken egg.
A male and female kiwi will remain mates for about 20 years, and the male is usually the one who incubates the eggs.
