That sounds very clever, but still hinges on one thing that you haven't actually addressed.The modern chicken descended from another closely related species of birds, the red junglefowl, but recently discovered genetic evidence shows that the modern domestic chicken is a hybrid descendant of both the red junglefowl and the grey junglefowl. This proves that others came before the chicken making them perfectly able to hatch the egg carrying the first chicken in existence. The chicken egg came before the chicken.
It depends entirely on how you define "Chicken egg".
Either, you define it as an egg that came from a chicken, in which case the chicken must necessarily have come before the chicken egg.
Or, you define it as an egg that contains a chicken, in which case the chicken egg must necessarily have come before the chicken.
The references to junglefowl, no matter how correct, are irrelevant.
