Detailed explanation-1: -While an ostrich lays the world’s largest bird’s egg, it is actually the smallest in proportion to the mother at just 2% of her body weight. In fact, kiwi eggs are six times bigger than other birds of the same size. In humans, a baby at full term is 5% of its mother’s body weight.

Detailed explanation-2: -The ostrich lays the largest egg in the world, with the average egg weighing three pounds and being six inches long. The largest egg in the world is laid by the ostrich. The average egg of an ostrich weighs about three pounds, which for perspective is the weight of about 24 chicken eggs!

Detailed explanation-3: -The largest ratite is the ostrich (Struthio camelus), from the plains of Africa and Arabia. A large male ostrich can reach a height of 2.8 m (9.2 ft) and weigh over 156 kg (344 lb). A mass of 200 kg (440 lb) has been cited for the ostrich but no wild ostriches of this weight have been verified.

Detailed explanation-4: -Ostrich eggs are the largest of all eggs, though they are actually the smallest eggs relative to the size of the adult bird-on average they are 15 cm (5.9 in) long, 13 cm (5.1 in) wide, and weigh 1.4 kilograms (3.1 lb), over 20 times the weight of a chicken’s egg and only 1 to 4% the size of the female.

Detailed explanation-5: -The Emus, a close relative of the ostrich, produce the second-largest egg. Measuring up to 5 inches long and 2.5 ounces in weight, these birds lay a beautiful large green egg. Native to Australia, they are also the second-largest bird in the world, standing tall at more than 5 feet.
