Ostrich eggs are the largest eggs laid by any living bird species. They come from the ostrich, which is native to Africa and is the world's largest bird. Ostrich eggs are typically around 6 inches (15 centimeters) in diameter and can weigh up to 3 pounds (1.4 kilograms), although sizes can vary.
These eggs have a thick, hard shell that is strong enough to support the weight of an adult ostrich. The shell is often speckled or textured, providing camouflage in their natural habitat. Inside the shell, the egg contains a large yolk and egg white, similar to the composition of chicken eggs but on a much larger scale.
Ostrich eggs are consumed as food in some cultures, and their shells are often used for decorative purposes, such as carving or painting. In addition to their culinary and artistic uses, ostrich eggs are also sometimes used for scientific research or educational purposes due to their large size and unique characteristics.
