Yes, but is a chicken egg one that’s laid by a chicken, or one that hatches the chicken? The answer to that question affects the answer to which came first
There was never any point where a non-chicken laid an egg that hatched into a chicken. Evolution doesn’t care about our categories, just as the rainbow doesn’t care about our colour words!

It’s one that hatches a chicken. An egg layed by a chicken is a chicken*'s* egg. If a chicken doesn’t come out of it, it ain’t a chicken egg.
It’s one that contains a chicken:
A chocolate egg is an egg that contains chocolate, not one that is laid by chocolate.
