Has to be the egg, something layed that egg to get something more like a chicken then it got mixed with another animal to make a actuall chicken

The theory of evolution states that species change over time via mutation and natural selection. Since DNA can be modified only before birth, a mutation must have taken place at conception or within an egg such that an animal similar to a chicken, but not a chicken, laid the first chicken egg. In this light, both the egg and the chicken evolved simultaneously from birds that were not chickens and did not lay chicken eggs but gradually became more and more like chickens over time.
