They referred to it as a "Chicken McNoggin" at Snopes.

As some reports go, the chicken head seems fully intact, so it's doubtful any harm came to anyone. It's not a foreign object since chicken parts are expected in a box of chicken parts. And she wasn't freaked out too bad, as she was posing with it for pictures.

Legally, you must prove actual harm to collect damages. I doubt the lady got anything more than a small amount of "freak out" compensation and a new box of McD's Mighty Wings.
