Ostrich Egg
Most of the time an ostrich egg will hatch under lights in an aviary, but some aviaries still let the mother hatch her own young.
Caring for the eggs is a duty divided between males and females. Males tend to watch over them in the night, while females of the mating group take turns during the daytime. The ostriches' egg measures 17 to 19 cm in length, and 14 to 15 cm in width. It weighs up to 1900 g.
