An age old question

[noxious]

A chicken can't emerge from anything but a chicken egg, and a pre-chicken can't lay anything other than pre-chicken eggs. It's all perspective, because the question is too ambiguous to get a single, clear answer.

The egg that was produced from a pre-chicken would have to be a pre-chicken egg, according to logic. But if a chicken emerges, it would have to have been the first chicken egg. Again, according to logic. According to genetics, the egg that hatched the first bird you want to call a chicken (there isn't just one type of chicken) would be the answer to that infernal riddle.

However, to answer the question as I read it, it would be the egg hands down.

Why?
Because dinosaurs laid eggs, and the question only said "the egg", not "the chicken egg", and since dinosaurs predate chickens by millions of years, eggs did also.

The question should read "Which came first, the chicken or the chicken egg?" to get the desired effect.

The egg did in fact come first. But if we take it a step further... on the basis of evolution than living organisims came before eggs :-\
