they just did
it was the egg

Put simply, the reason is down to the fact that genetic material does not change during an animal's life.

Therefore the first bird that evolved into what we would call a chicken, probably in prehistoric times, must have first existed as an embryo inside an egg.

Eggs existed long before birds / chickens did. Remember, the dinosaurs laid eggs, too. So the egg HAD to be first.
