Re^2: Which came first?

[goibhniu]

I thought about the same, but got confused when thinking about sexual reproduction (having been a teen male once, you can understand how sex might confuse me).

A female ${animal that came before a chicken} produces a mutant egg which can be said to be a half-chicken. Did that egg count as a chicken egg? Where's the father who fertilizes that egg? Is the first chicken a half-breed and thus not a full chicken? What kind of eggs did that animal produce? After how much mixing did the half-breeds produce a mother with a chicken-egg and a father with his contribution also 100% chicken?

Regardless, after about 30 sec, I came to the same conclusion. The chicken-eggs (and other stuff) were being produced long before the first chicken.

This is a fairly interesting question by itself, but I would offer two objections with regard to the original question:

1. Any egg that would produce something that would be considered a chicken is still an egg.

2. The OP doesn't stipulate any kind of egg, and we can probably safely assume that any direct ancestor(s) to a chicken also reproduced by laying eggs.
