About the Domestic Chicken

Class: Aves  
Order: Galliformes  
Family: Phasianidae  
Genus: Gallus   
Species: gallus domesticus  

Domestic chickens are found wherever humans keep them. They have had much of their behavior bred out of them by the domestication process. They are now less capable of fending off predators, for instance, and less aggressive toward each other.
