Breeding pairs are able to produce two batches per season with approximately 15 eggs per nest depending on the season.
Ostriches react quickly to rain and the availability of food.
Those in areas close to the equator appear to have an open breeding season while those further away breed seasonally. Partly hatched eggs can be removed from the nest after about two weeks and put in the incubator. At least five eggs should be left in the nest for the breeding pair to hatch if they have to rear chickens. At different stages various factors have an influence on the hatchability of the eggs. Age of breeding birds Males are usually sexually mature from three and a half years of age and females from two and a half years.
