This is a dumb question. The answer is the Egg, because that’s how evolution works. Mutations happen in the egg, not after their born like Ninja Turtles. It went Proto Chicken,>Egg>Chicken.
Not even necessarily “proto-chicken”, the definition of species is operational and breaks down at this level. It’s like asking “how strong is this wind?” with a single air molecule. For species, the proto-chicken and the chicken separated by a single generation would be able to reproduce just fine, you need to pick further points to discern
uh, mutations do happen after they are born (i’ve been irradiated a few times i’m sure i’ve got one or two). they just have to be in the gametes to be evolutionarily important.

It’s a language question, as you’re asking that we define whether a (Chicken) Egg is an egg laid by a chicken or an egg that hatches into a chicken.
