So that article went a bit all over the place but this is a discussion I really like to kick around with.

1- everything starts first as an egg and wether we like it or not the egg is developed in a womb some are just ejected in a hard shelled egg that survived the birth canal and some a soft shell that is meant to be destroyed upon exiting.

2- evolution can't be ignored as an extremely long process that humans have tried everything within their power to speed up to provide ourselves with convenience. The sheer Variety of "chicken" we now have is a testimony to that.

3- Birds lay eggs and eggs are easy prey items for a human though it likely was more dangerous than it is now (with the exclusion of some breeds being un-trickable and viscously protective of their offspring that leaves them largely, off the table for us)

4-if we're to believe All life on earth evolved from single celled organisms and that nature allows us to Only breed with genetically similar counterparts then enforcing the ideal that evolution is a fast rather than slow process for a species as diverse as the chicken (or fowl) depending on how your able to divvy thing up goes against well established science with recorded proof of genetic engineering taking place to achieve New species of animals that take generations of modifications from the DNA collection of males and females that are compatible enough to allow for a new Catagory of breed to be developed in either a natural or artificial womb/egg.

In conclusion.... The eggs ALWAYS are first no matter the species of animal including the lesser life forms we typically refrain from giving an animal title to but agree to call a lifeform
