Ostrich eggs are the largest of all eggs, [4] 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.

Masai ostrich eggs are large (grapefruit-sized) and white in color. [10] [18] They measure 14–16 cm and weigh between 1.0 and 1.6 kg. [19] Egg hatching occurs during October and November, when eastern Africa experiences brief periods of rainfall that generates edible plants that are the Masai ostriches primary food source. [10]

Scandinavian traditions also involved boiling eggs with flowers inside onion skins to colour them. [1] Another type of egg decoration is the Hungarian practice of egg shoeing, which requires goose eggs and miniature horse-shoes, made of iron or lead. The current world record of egg shoeing is 1119 shoes on a single ostrich egg. [6]
