ok, look..

First off, let's clear the air and state a fact:
All creatures are born from eggs.

Fish came first, laid eggs in water. The comes Amphibians..They are different than fish because they need water only in order to reproduce, because their eggs are like fish, and need water to help fertilize and develope. Other than that, frogs live on land, right? So here comes this huge developement with Reptilia.. The amniotic egg, which has fluids inside and a thick shell to protect it in some cases, so that animals don't need water at all anymore in order to reproduce, meaning truly terrestial (land) creatures were born.

Then Mammalia and Aves fork off reptiles, and chickens belong to Aves. They are descendents of reptiles, so they also are amniotes, and have amniotic eggs, like humans.

Just think about this logically for a second here. It is impossible for a creature to exist before it has the capacity to be created, because things don't just begin in media res, it has to have a start point. If you look back into the evolution of species from the birth of a cell into humans today, there is an unbroken chain.

Eggs came before chickens even came into being as a species, so I find it hard that there is any intelligent possibility for it to be otherwise. An explanation for a chicken becoming a species is it specialized, or got seperated geographically, and the gene pool changed over time, and thus the chicken became so different from what it was before it can be considered it's own species.

Textbook example: Darwin's swallows.

All originally the same species, but specialized on certain Galopagos islands to treat unique needs, like say ones with broader, larger beaks can crush shells more easily to get food. Those who can't die off, the gene pool changes, and once it can produce viable offspring that are incompatible with the previous species, new species is born. Just like that. It doesn't even have to take millions of years.

Which in the end once again concludes the point, the egg came first, not the chicken.
