According to a U.S. Poultry Council report released Monday, the collective efforts of the world's 16 billion chickens have yet to yield any appreciable results. 'For thousands of years, chickens worldwide have put a tremendous amount of energy into their various activities, which include flapping, squawking and pecking with a great deal of vigor,' the Poultry Council report read. 'But it remains unclear what has been accomplished as a result of their unfocused efforts.'
