Scientific Name: Gallus gallus domesticus
Chickens aren’t completely flightless—they can get airborne enough to make it over a fence or into a tree. With 25 billion chickens in the world, there are more of them than any other bird species.
A mother hen turns her eggs about 50 times per day and can lay more than 300 eggs per year. The record number for eggs laid by a chicken in one year is 371.
Mother hens talk to their chicks while they’re still in the eggs, and the chicks can chirp back while in the shell.
Chickens have prehistoric roots and are the closest living relative of the Tyrannosaurus Rex.
