A viable bird egg (as opposed to a non-viable egg: see addled eggs) consists of a number of structures.

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.

[4] [a] One source states that a generalized gull's egg is approximately twice the size of a chicken's egg. [5] Egging is the prehistoric practice of foraging wild-bird eggs.
