How Big Is an Ostrich Egg?

Ostrich eggs are approximately 6 inches in circumference, about 5 inches long and weigh around 3-5 pounds. An ostrich egg is equal to approximately 24 chicken eggs.

The ostrich lays the largest eggs of any bird living today. There have been larger eggs laid by the elephant birds and giant moa, but these birds are extinct now. In the wild, ostrich eggs are incubated in a hole that is 12- 24 inches deep and normally holds 20 eggs. The eggs are covered up and take about 42 days to incubate. When the eggs are incubating, the females sit on the nests by day because their more drab colors blend into the surrounding area better and mask the nest. The males sit on the nests at night for the same reason. Their black feathers are harder to see at night.
