In the nature living things evolve through changes in their DNA.in an animal like a chicken,DNA from a male sperm and a female ovum meet and combine to form a zygote-- the first cell of a new baby chicken.the first cell divides innumerable times to form all of the cells of the complete animal.in any animal,every cell contains exactly the same DNA,and that DNA comes from the zygote.
Chickens evolved from the non-chickens through small changes caused by the mixing of male and female DNA or by mutations to the DNA that produced by the zygote. these changes and mutations only have an effect at the point where the new zygote is created.That is,two non-chickens mated and the DNA in their new zygote contained the mutation(s)that produced the first true chicken.that one zygote cell divided to produce the first chicken.
Prior to that first true chicken zygote,there were only non chickens.the zygote cell is the only place where DNA mutations could produce aa new animal,and the zygote cell is housed in the chickens egg. so, the egg have come first.

It's a trick question.
The chicken had to come from somewhere but so did the egg. You'll never get the right answer.

I would say that egg came first before the chicken.Chicken is the result of cross breedings of pre-hestoric two non-chickens.Thus I would say that egg came first.

As I've said before, it depends on how you look at it. From a religious stand point, the chicken came first, because God (or Allah, whoever you worship) created the chicken first.
From a scientific standpoint, the egg came first. This is because all genetic changes - adaptations and mutations - occur in the embryonic stage. A creature born a reptile can not become a chicken during it's lifetime - it's impossible. However, a creature that was not a reptile but not quite a chicken could have produced offspring that underwent enough genetic changes to overstep the species boundary to the point where it became a whole new species (i.e.- a chicken).

This question has been a legend. Biblically speaking, God created chicken and then it laid eggs. From then on the eggs became chickens and the whole process starts all over again.
