Which living organism has the largest single celled egg in the world?

sunnysidesyl, haha, now let me tell you that chickens have personalities too! and pigs, goats, sheep, cows...

MoodyChef92025, The kiwi from New Zealand (not Australia) lays the largest egg for the size of the bird. 500 years ago the answer to the question would have also been a New Zealand bird, the moa but they became extinct not long after the Maori 's arrival . They were twice the size of an ostrich and also flightless and preyed upon by the largest bird ever known, an eagle that died out with the moas.

cool big eggs must fry

Player #53329429, Hey Moody, The Kiwi Bird belongs to New Zealand not Australia. Did you mean the Cassowary?
