The exact definition doesn’t matter though, every chicken whether the first or the last, or from the blurry zone between proto-chicken and chicken, has many much older eggs in it’s ancestry. Probably somethig fish something.
Revolitionary single mutations do occure sometimes and can mean speciation, so in some cases, there can be one individual that is the true first of the new species.

The point is that there’s no single generation where the species went from not a chicken to a chicken. That’s not how evolution works
No the point is exactly what i think , in exactly the way that i think it. I understand exactly entirely and completely how evolution works. /s
