Kiwi eggs can weigh up to one-quarter the weight of the female. Usually, only one egg is laid per season. The kiwi lays one of the largest eggs in proportion to its size of any bird in the world, [34] [a] so even though the kiwi is about the size of a domestic chicken, it is able to lay eggs that are about six times the size of a chicken's egg ...
Kiwi chicks are superprecocial, and are abandoned by their parents after hatching. After ten days, chicks venture out of the burrow to hunt. Most chicks are killed by predators in the first six months of their life. Great spotted kiwis reach full size at year six. Unlike most birds, female great spotted kiwis have two ovaries. Most birds have ...
The little spotted kiwi has a length of 35 to 45 cm (14–18 in) and the weight of the male is 0.88 to 1.36 kg (1 lb 15 oz – 3 lb 0 oz) and the female weighs 1 to 1.95 kg (2 + 1 ⁄ 4 – 4 + 1 ⁄ 4 lb), making it the smallest species of kiwi. [7] Their feathers are pale-mottled grey, with fine white mottling, and are shaggy looking.

Kiwi are notable for laying eggs that are very large in relation to their body size. A kiwi egg may equal 15 to 20 percent of the body mass of a female kiwi. The smallest species of kiwi is the little spotted kiwi, at 0.9 to 1.9 kilograms (2.0–4.2 lb) and 35 to 45 centimetres (14–18 in). [18]
Eggs of: ostrich, emu, kiwi and chicken. Egg size tends to be proportional to the size of the adult bird, [citation needed] from the half gram egg of the bee hummingbird to the 1.5 kg egg of the ostrich. Kiwis have disproportionately large eggs, up to 20% of the female's body weight. [18]
A female common ostrich can distinguish her own eggs from the others in a communal nest. [67] Ostrich eggs are the largest of all eggs, [ 68 ] 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 kg (3.1 lb), over 20 times the weight of ...
