Ah, an ages old question!
Chickens evolved over time and there must have been a point at which the parent wasn’t a modern chicken but the offspring were. A simple view is that at whatever point the threshold was crossed and the first chicken was hatched, it had to hatch from an egg. The type of bird that laid that egg, by definition, was on the other side of the threshold and therefore not technically a chicken — it may be viewed as a proto-chicken or ancestral chicken of some sort, from which a genetic variation or mutation occurred that thus resulted in the egg being laid containing the embryo of the first chicken.
In this light, de facto, the argument is settled and the egg had to have come first.

If you believe in evolution, then the egg came first , because chickens evolved from fish, amphibians, etc. , fish had eggs way before chickens existed !
If you believe in creationism, then the chicken came first because it was created by God, then started to lay eggs.
Many scientists believe in evolution, although some do believe in creationism.
