The answer to this age-old question is: both and neither cam first.
Allow me to explain. Evolution is a process of organisms gradually having their characteristic changed and selected over many generations. The chicken evolved from something that looked a little different and had eggs that looked a little different. You can trace back the evolution of chickens using DNA sequences and see that it took chickens 3.8 billions long years to look the way they do today and have the eggs that they do.
For example, there wasn’t just one point in time where the ‘egg’ suddenly showed up. Instead there were probably many thousands or millions of years where the offspring slowly became more egg-like. Chicken and all birds actually are descended from dinosaurs.
Nothing in the universe came first, everything just changes form. I the case of chickens and evolution, it took a long time and many, many, gradual changes.
