wich came first?

i cheated i found this lol... Prior to the arrival of the chicken, a pre-chicken creature that was at least one generation away from our present-day chicken, laid an egg that contained an embryo with DNA consistent with the “new” aviary creature known as chicken. Therefore, the egg that contained the newly evolved chicken preceded its hatching. In other words, prior to the arrival of the first zygotic mix of male and female pre-chicken DNA that combined or mutated to form today’s chicken, there were only non-chickens. The DNA mutations occurred at the cellular level in the zygote developing inside the egg. Therefore, the egg clearly preceded the chicken.
