What kind of egg? The egg certainly came before the chicken, as birds evolved from reptiles and reptiles lay eggs. We could go further back and say fish lay eggs.

However, if the question involves a chicken egg, then the answer is the chicken- a chicken is required to lay a chicken egg. The egg the chicken hatched out of was the egg of a different animal, evolution being the mutation of genes.

It should also be pointed out that this isn't general chess discussion.

Edit: I did not make this thread! The OP deleted his post.

Nytik's nailed it -- I came here to say precicely that.

 The answer to the question or the fact that the thread is posted in the wrong forum?  I'll assume you don't attend to such trivial matters.

Nailed it all, although I'd not noticed which forum it was actually in.

  That's a great answer (if you're not a creationist, anyway)!

The one thing that strikes me as debatable is the way you define the 'kinds' of eggs.  Is it not as valid to define the egg by what comes out of it, as opposed to what it came out of? 

Well, the concept of a chicken egg had no meaning before a chicken existed so I'd say it's more valid to assign the egg type based on the layer not what hatches out of it.  An unfertilized chicken egg (like you'd buy at the store) isn't a yolk egg -- it's still a chicken egg even though no chicken will ever come out of it.

In either case, the type of egg was not specified in the question so the aspect that is debatable (how the type of egg is determined) is also not relevant to the original question.

an egg is a cell - a macroscopic literal cell.   And a chicken itself is nothing but an  aggragation of cells. 

So your question is, which came first - a cell or a group of cells.

To be clear, that is not in the general sense -- as in "Which came first:  Cells, or groups of cells?", but in the specific sense -- as in "Which came first:  Chickens or eggs?". 

well, a chicken egg is just a chicken in a different form. 

Not an unfertilized one.

DeepGreene:

I would respond to your point, but it looks like you've already recieved your answer earlier on in the thread. (Thanks TheGrobe!)

Eberulf is just trying to contradict the answer, but trying unsuccessfully. (Thanks again, TheGrobe! )

God created the Chicken first

I can buy that.  So in theory, a chicken could hatch from an iguana egg, but an iguana could not lay a chicken egg.  Works for me.  :)

DeepGreene: Precisely!!

Wow, this post is so short, it could be considered spam. What to add?

Oh, here's something:

Scarjo- Never, ever post on the forums again.

It's obvious.

Which came first - the fried chicken or the fried egg.

The question is what came first the lesser water boatmen, or the greater water boatmen.

I think that the question posed by KAKROACH is usually understood to mean which came first the adult or the egg.

the big bang!

I post, therefore I am.
