Chicken came before the egg.
So the riddle seems to be solved.
BRITISH scientists believe they have cracked the answer to the age-old question of which came first, the chicken or the egg?
Researchers have found that a protein called ovocleidin (OC-17) is crucial in the formulation of eggshells, and it is produced in the pregnant hen's ovaries, the Daily Express reports.
Therefore, the answer to the conundrum must be that the chicken came first.
Using a high-tech computer to look at the molecular structure of a shell, the team of scientists from the Universities of Sheffield and Warwick found that OC-17 acts as a catalyst, kick-starting the conversion of calcium carbonate in the chicken's body into calcite crystals.
They make up the hard shell that houses the yolk and its protective fluids while the chick develops.
"It had long been suspected that the egg came first but now we have the scientific proof that shows that in fact the chicken came first," said Dr Colin Freeman, from Sheffield University.
"The protein had been identified before and it was linked to egg formation but by examining it closely we have been able to see how it controls the process."
But the researchers have not yet managed to answer how the protein-producing chicken existed in the first place.

The chicken egg comes from the Amniote eggs, they were called like that because their eggs had an amniotic membrane.
The first Amniota appeared about 340 million years ago, while Aves 150 only million years ago.
Thus the egg came first.
We could also take in account earlier types of eggs, going back to out common ancestor with the Arthropods and Mollusca, 555 million years ago

If you believe in and follow the Bible, you argue the Chicken came first (all life was created at the same time)
If you believe in and follow Evolution/Darwinism, you argue the egg came first (eggs for other species existed long before chickens evolved into what they are today)
The real question is not which came first, but which tastes better?

Bazzy: That's cheating. You're replacing semantical values. What the question obviously means is "chicken or chicken egg".
Still, the question isn't easy to answer in evolutionary terms because there's no clear divide between what a chicken is today and its closest non-chicken ancestor. It's not like at one point a dinosaur gave birth to a chicken egg.
Hmm... So is there something like a /bin/esh?

The question would be pointless if it was "chicken or egg laid by a chicken", smartypants.
IMO the question is pointless anyways
If the original question implies no evolution and infinite time, it would be like asking the solution of this limit:
lim ⌊ 1 + sin πx ⌋
x→-∞

This takes it off topic... :P

So the shell came first or the script?

It's not really quite the same. There's an upper limit to the age of the chicken species (well, unless the species transcends time, somehow), so the limit of the actual function at -inf. isn't undefined because the limit doesn't exist, but because the function is defined in a closed interval. You just need to find where the interval begins and evaluate the function there.
