Chicken and People

There is some thought that is bothering me... and hopefully some of you could answer this.

Considering the entire history of the human race, Do you think chickens has already outnumbered humans? Consider the chickens that we eat constantly in those fastfood chains. Counting people and chickens since the dawn of history, do you think chickens has already outnumbered people?

Tough one huh? Could someone answer this for me please....
