The Strongest Egg in the world

With our breeding ostriches laying eggs since we are in the middle of the breeding season - I want to share with you how strong ostrich eggs are.

The biggest bird in the world lays the biggest egg in the world. One ostrich eff can weigh about 1,5 kg. An adult ostrich can weigh up to 180 kg.
The male ostrich sits on the egg at night and the female during the day to incubate them. She is grey and he is black for camouflage so that predators can not see it is ostriches sitting on eggs.

The eggs have to be strong enough to carry the weight of the adult birds when they incubate them. One ostrich eff can take the weight of about 220 kg vertically and 120 kg horizontally. This means you can stand on ostrich eggs and they will not break. The eff shell is 2 mm thick which sounds like nothing but is the strongest shell on any egg.
