Everyone here seems to be missing the point of the question. The chicken isn't the key point. It stands in for all egg laying animals. To rephrase the question: how is it possible that an early species was able to develop egg laying abilities, considering the problem of that animal not having been born from an egg? I suspect the real answer has something to do with fish ...

  • Shells are soft gloopy things laid in lakes
  • Evolutionary advantage: Eggs laid on the edge of lakes away from water predators
  • Evolutionary advantage: Harder eggs survive longer further out of water
  • Evolutionary advantage: Harder land eggs give rise to amphibous/land animals
  • Evolutionary advantage: Amphibous/land animals lay land eggs
  • etc.
