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 expected to be sold in three, five or 10 pieces with prices likely starting at $3, according to Lynne Collier, an analyst with Sterne Agee.

A spokeswoman for McDonald's confirmed the test in Chicago would start this week but said there weren't any plans yet to bring the wings to other cities. Fast-food chains typically test items in select markets before taking them national. But for McDonald's, which has 14,000 U.S. locations, adding chicken wings to the permanent lineup could be tricky.
