What came first, the chicken or the egg?

Martin R. from Aardvarchaeology has the answer.
"What came first, the chicken or the egg? Easy, you say, eggs were laid by other animals aeons before the first chicken saw the light of day.

But what came first, the first chicken egg or the first chicken? This boils down to whether a chicken egg is one laid by a chicken or one out of which a chicken can hatch."
