A new item for McDonald's is the Chicken Big Mac, however, they are not available in the States at this time. You can only get them in Austrailia, I believe it is, for now.

I love the original Big Macs, and these new chicken Big Mac's sound pretty good to me.
I hope they are available in the USA one day!
