NEW YORK (AP) — 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.

Prices for chicken wings have been climbing over the past year, reflecting an increase in the number of restaurants serving them, said David Harvey, an agriculture economist who specializes in poultry and eggs at the U.S. Department of Agriculture. In December, the cost of wings in the wholesale market in the Northeast was 26 percent higher than a year ago.

Rather than becoming a permanent part of the menu, McDonald’s could offer the dish for a limited time; the chain has said it plans to ramp up the frequency of such special offers as a way to give customers more variety. But whether it will offer “Mighty Wings” even on a limited-time basis will likely depend on McDonald’s ability to get wings at reasonable prices, Collier said.

The test comes amid intensifying competition for McDonald’s, which for years had outperformed rivals such as Burger King and Wendy’s with a steady stream of new menu items, such as snack wraps, fruit smoothies and specialty coffee drinks.
