On a literal note: the Egg, since we all know that chickens evolved from T-Rexes, and they laid eggs.
On a slightly different note: The entire subject could be viewed as a metaphor for human male/female sexual relationships and the tensions that are paired with it. The Egg obviously represents the female, being symbolic for the egg produced within female sexual organs. The chicken refers to the man, relating to the slang 'cock' and how men generally refer to their penises as such. Now, the question is, which came first, which, of course, could be viewed as who had an orgasm first. Now is where it gets tricky, since everyone is different and has different standards. In many situations, the woman will orgasm first, though it is generally believed that men orgasm more quickly than woman. I am no saying that this is true or not, but that it is the general opinion. As for my argument, I believe that the woman will have the first orgasms, since chickens evolved from T-Rexes (which laid eggs) and therefore means that they came first.
