Did the chicken lay egg?

This is a bit of a trick question! Here's why:

* The chicken-and-egg dilemma: The question of whether the chicken came first or the egg is a classic philosophical problem. There's no simple answer.

* Evolutionary perspective: Chickens evolved from non-chicken ancestors. At some point, a creature that wasn't quite a chicken laid an egg that hatched into a chicken. So, in a way, the egg came first.

* Technicality: A chicken is a bird. All birds lay eggs. So, a chicken, by definition, would have to lay an egg.

Ultimately, the answer depends on how you interpret the question!
