I'm sure if Pikachu had been in the poll, the outcome would have been decided long ago. lol
On topic and to be serious: This is the exact analogy to the mother and the child. The child grows and becomes an adult just like the egg grows into a chicken. We're being caught in a loop, and hence, this age old question.
I'm not a philosopher but I will hazard a guess here:
If we liken the egg to the inchoate form of an idea, then the chicken must be the mature form - the revolution. So in that sense, the egg comes first.
Now when we say "but chicken come from eggs", we are making generalisations while solving a specific problem. Which individual chicken and which eggs? The chicken individual here doesn't come from the egg in consideration. So in temporal position, the chicken must have come first.
Now if we extend the question to the "origin of chicken", no one knows... for sure. The reason is that new researches always overturned common and established beliefs. For example: A while ago, we believed that the flightless birds such as emus and ostriches once shared a common flightless ancestor. A new research suggested the contrary: in fact, each species lost its flight after diverging from ancestors that did have the ability to fly. [

Thinking of the Bible, one may argue that God created a pair of rooster and hen in the beginning, and so the chicken population expanded (just like Adam adn Eve, and so, us). But let's not get into the religious aspect of this. lol...
