The incubation period for ostriches is 40-42 days. About 1 week after the ostrich mates, the female begins to lay eggs. Usually 1 egg is laid every other day or two days until there are 12-16 eggs in the nest, then the long incubation process begins, which is carried out alternately by male and female ostriches.

Nests are built on the ground and all females lay their eggs in the same nest. Each female lays 10-12 eggs, and the number of eggs per clutch can reach 25-30. The eggs are large, yellowish-white, measuring 152 x 203 millimeters and weighing about 1,300-2,000 grams. The female incubates them during the day and the male bears them at night.
