Eggs predate chickens by millions of years. Dinosaurs laid eggs long before chickens existed, as did prehistoric fish. The first chicken was a mutated fowl of some sort and likely came from an egg. Any way you slice it, the egg came first.

So in a nutshell (or an eggshell), two birds that weren't really chickens created a chicken egg, and hence, we have an answer: The egg came first, and then it hatched a chicken.

The egg.  There were animals that laid eggs long before there were birds, let alone chickens.  There were insects, arachnids, fishes, amphibians, and reptiles before there were birds.
Is that intelligent enough?

The chicken did.  An egg would need to be  kept warm by a mother hen, and a baby chick once hatched would need a parent to shelter them and teach them what to eat, how to watch for danger, how to be a chicken.  An adult chicken would already be pre-programmed with the knowledge necessary to survive and thrive, and how to lay eggs and raise babies.

Two answers.

1.  The egg.  If you could go back to the first chicken, you'd see it was a genetic mutation that created it.  Its parents were not chickens (because then it wouldn't be the first chicken, would it?)  The mutations would appear in the egg, so the first chicken egg appeared before the first chicken.

2.  The egg.  Insects were laying eggs millions of years before there were chickens!
