noun. A collection of eggs from different birds. A collection of eggs from different birds. The definition of an egg is the female reproductive cell in many animals or the thin-shelled oval body laid by hens and other animals. An example of an egg is what gets fertilized during a female's ovulation.
The answer, they say, is the chicken. Researchers found that the formation of egg shells relies on a protein found only in a chicken's ovaries. Scientists have discovered that eggs can only have been laid by chickens, thus solving the puzzle. Therefore, an egg can exist only if it has been inside a chicken. The protein-called ovocledidin-17, or OC-17 - acts as a catalyst to speed up the development of the shell. This hard shell is essential to house the yolk and its protective fluids while the chick develops inside.
