McDonald's chicken wings

NEW YORK — First there were McNuggets. Then there were Chicken McBites. Now McDonald’s could be adding “Mighty Wings” to its chicken menu.

The world’s biggest hamburger chain is set to expand its test of chicken wings to Chicago this week, after a successful run in Atlanta last year. The wings are being sold in servings of three, five or 10 pieces with prices starting at $3, according to Lynne Collier, an analyst with Sterne Agee.
