In the run-up to Super Bowl Sunday, millions of American football fans can rest assured: there is no looming shortage of their beloved chicken wings. The National Chicken Council estimates that the nation will wolf down 1.23 billion chicken wings over Super Bowl weekend, or nearly four wings for each and every American. But fears that restaurants, bars, fast food outlets and supermarkets will run out of the savory snack -- served baked, fried or grilled, most often with ranch or barbecue sauce -- are unfounded, the industry group said Thursday.
