The female common ostrich lays her fertilized eggs in a single communal nest, a simple pit, 30 to 60 cm (12–24 in) deep and 3 m (9.8 ft) wide, [1] scraped in the ground by the male. The dominant female lays her eggs first, and when it is time to cover them for incubation she discards extra eggs from the weaker females, leaving about 20 in ...

The male will often spend more time incubating the nest than the major female. [10] [4] An upwards of 18 ...
The male and female alternate to sit on the eggs with the female doing duty in the day and the male in the night. Some birds can lay up to 100 eggs during the breeding season with an egg being laid every one or two days. During this period the male ostriches become very aggressive protecting both the female and the eggs. [citation needed]
A male ostrich moves about its breeding pen near the farmhouse at American Ostrich Farms. McCoy said that all of the farm’s breeding hens are over 2 years old.
Ostrich farming grew out of this need, and humans harvested feathers, hides, eggs, and meat from the ostrich. Emu farming also became popular for similar reasons and for their emu oil. Rhea feathers are popular for dusters, and eggs and meat are used for chicken and pet feed in South America. Ratite hides are popular for leather products like ...

The female common ostrich lays her fertilized eggs in a single communal nest, a simple pit, 30 to 60 cm (12 to 24 in) deep and 3 m (9.8 ft) wide, [66] scraped in the ground by the male. The dominant female lays her eggs first; when it is time to cover them for incubation, she discards extra eggs from the weaker females, leaving about 20 in most ...
The only living mammals that lay eggs are echidnas and platypuses. In the latter, the eggs develop in utero for about 28 days, with only about 10 days of external incubation (in contrast to a chicken egg, which spends about one day in tract and 21 days externally). [11] After laying her eggs, the female curls around them.
