Chicken Fingers?

Now don't get me wrong, I love me some chicken. I am however a little confused as to why they are called chicken fingers. I didn't grow up on a farm, but I do know chickens do not have fingers. Chickens have wings, those make sense. Chickens have legs, and while they are skinny they still make sense. But they don't have fingers, so where are chicken fingers coming from? Is that what they mean by genetically modified? They have fingers growing on the backs of chickens in some lab somewhere? Maybe I am asking too many questions and when something tastes as good as chicken fingers I should mind my own business before PETA shuts down the chicken finger labs or something.
