Big Chicken == Tyson, I believe, at least in the US.

Big Strawberry == Driscoll's, at least on the west coast. And those are some pretty undistinguished strawberries.

No, Big Chicken == Shaquille O'Neal in the US. His picture is right there on the official Big Chicken Dot Com website and everything.

I stand corrected. And he is big, so that’s an apt spokesman.

Check out his hands. That’s a full sized chicken sandwich he is holding, and it looks like a McNugget on a slider bun.
