My thoughts on this whole issue. Yes the chicken evolved from something that slowly approached on a genetic level what we now know to be the chicken. But, at this last step prior to the egg being known as a chicken egg, it was in fact the egg of the ancestor creature and not a chicken egg since it was created from this ancestor and not from a chicken in the genetic sense. Once the chicken hatched from this ancestor's egg, it was then able to reproduce using its own, i.e. chicken, eggs. So, my answer is that the chicken came first. Make sense to anybody else out there? I see no paradox here at all.
