The egg. Now a team made up of a geneticist, philosopher and chicken farmer claim to have found an answer. It was the egg.
Put simply, the reason is down to the fact that genetic material does not change during an animal's life.
Therefore the first bird that evolved into what we would call a chicken, probably in prehistoric times, must have first existed as an embryo inside an egg.
Professor John Brookfield, a specialist in evolutionary genetics at the University of Nottingham, told the UK Press Association the pecking order was clear.
The living organism inside the eggshell would have had the same DNA as the chicken it would develop into, he said.
"Therefore, the first living thing which we could say unequivocally was a member of the species would be this first egg," he added. "So, I would conclude that the egg came first."

Chickens evolved their reporduction process.
In other words the chicken came before the egg
