The chicken came first.
How come do you know that chicken was first to born though ? without the egg the chicken would not be born , this been debate all over the years , it causing a confusion on some people , but nevertheless in my perspective and what i believe is the egg came first.
When anyone tracks the formation and development of the chicken or the egg, he can see that the process is involved and complex. The formation of the chicken inside the egg, shows that the chicken is around even at the same time the egg exists. But when the egg has outgrown its usefulness, it is discarded, and returns into the dust of the earth. However, this ultimately happens to the chicken as well.
The point is, you always have the chicken, even if it is in development inside the egg. But the chicken goes on without the egg, often for more than a decade... sometimes more than two decades.
Since eggs are formed inside of chickens, but there is a new chicken forming inside the egg inside the chicken, chickens form inside chickens. Eggs are simply part of the process of the development of a chicken.
Understanding all this shows that the whole question is moot, and is a distraction from the real question >>>
Where do chickens come from in the first place?
