Entrez Taxonomy
 
    
        
            The chicken (Gallus gallus) is a type of domesticated fowl, believed
            to be descended from the wild Indian and south-east Asian Red
            Junglefowl.
            
  
            With a population of more than 24 billion in 2003, there are more
            chickens in the world than any other bird. They are used to produce
            two sources of food: their meat, and their eggs.
