Ostrich The ostrich breeding industry around Oudtshoorn was started during a lengthy drought period in this area, when the suffering farmers discovered that ostriches were thriving despite the drought and even delivered tasty meat.
The breeding animals reach sexual maturity after two to three years. Mating occurs all year long, but mainly from April to September.
As soon as the male has scraped a sufficiently deep nesting trough into the ground, the female lays one egg a day, until there are 10 to 15 eggs.
From the laying time, incubation time lasts about 42 days. Males and females take turns, but the males usually do the "night shift", because they are well camouflaged with their dark feathers.
Ostrich eggs are the biggest bird eggs in the animal world. Nevertheless, in proportion to the size and weight of an ostrich, they are the smallest eggs of any species.
An average egg is about 15 cm long, 12 cm wide and weighs about 1.5 kg. Although the shell is only 2 mm thick, the egg can sustain a weight of up to 120 kg.
