This question appears regularly in the question file, so let me take a shot at it.
In nature, living things evolve through changes in their DNA. In an animal like a chicken, DNA from a male sperm cell and a female ovum meet and combine to form a zygote -- the first cell of a new baby chicken. This 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 non-chickens through small changes caused by the mixing of male and female DNA or by mutations to the DNA that produced the zygote. These changes and mutations only have an effect at the point where a 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 true 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 a new animal, and the zygote cell is housed in the chicken's egg. So, the egg must have come first.

I'd have to say the chicken because how can an egg appear before any living organism. A chicken could have easily evolved over time from a different species that we are unfamiliar with. And thus, once the it evolves into a chicken, then can there be an egg.

Definitely the egg. Living things have been making eggs or seeds ever since the dawn of multicellular life. The chicken's egg differs from that of the sea slug in being fertilized internally, laid on dry land, and having a hard shell. The basic concept, of a capsule in which an embryo can develop and be nourished, must have been an outrageous success, as now very few complex organisms reproduce any other way.

I think that one was already answered here somewhere.....
Personally, I think it was the egg. Yes, definitely the egg. That is why we have omelette's for breakfast and chicken for dinner.
