      Technically the process of evolution means there was no first chicken or first egg, as it’s hard to draw the line at when the animal which preceded it evolved into a chicken. But for the sake of resolving the question, my logic would be….
      a chicken had to be born from an egg and eggs have also been around for millions of years before chickens evolved (since birds evolved from dinosaurs), so I would argue the egg wins!🐣🥇

      Other egg laying organisms such as reptiles existed long before any bird so technically the egg wins.
      And semantic technical victories are the best kind 😁

      The Classic Conundrum! or at least, supposedly.

      1. eggs them selves have been around for millions of years before chickens.
      2. Chickens would have evolved from another animal, meaning they are slightly different genetically. these changes would then cause the embryo (inside the egg) to develop into a chicken. This then resulted in the first Chicken, but this would have hatched from an egg laid by a slightly different bird in terms of genetics. Therefore the egg must have come first?

      3. In the case of the first chickens egg however, definitely the chicken.

      😊👍

      As others have said, technically there was not a sudden arrival of a chicken (as we know it) or an egg (as we know it, in terms of having a chicken in it). Evolution acts over millions of years. Chickens evolved from other creatures like reptiles, which laid eggs. Over time, many many genetic mutations and many many generations of evolution formed what we know as a chicken from the egg. So, technically ‘an egg’ came first, which hatched into a chicken but this came from a non-chicken creature and then the first ‘chicken egg’ came from that first chicken. You could argue either, depending on what you’re defining as an egg and a chicken!

      Assuming we are talking about the first ever fertile domestic chicken (Gallus gallus) and the specific egg it hatched from; the egg wins hands down for all the reasons Matthew gave. As an aside, the domestic chicken apparently diverged from the red junglefowl about 58,000 years ago:

      I still don’t think it would have woken me up in the morning though! Have a listen to the audios here:

      Great question! I have no idea, but think I would go for the egg, if forced to chose!

      Haha I am reading the other answers with much interest. I would probably have to say egg too based on the argument by Alex!
