The default color of vertebrate eggs is the white of the calcium carbonate from which the shells are made, but some birds, mainly passerines, produce colored eggs. The pigments biliverdin and its zinc chelate give a green or blue ground color, and protoporphyrin produces reds and browns as a ground color or as spotting.
After mating, the male builds a nest where each female lays eggs. The nest is a simple scrape in the ground, lined with grass and leaves. [15] The male incubates from ten to 60 eggs. The male will use a decoy system and place some eggs outside the nest, then sacrifice these to predators so they do not attempt to get inside the nest.

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]
