Chicken vs Egg - Mander

At which point does an egg of non-chicken become an egg of chicken?
Is a “chicken egg” an egg laid by a chicken, or an egg that will hatch into a chicken?
The former, otherwise it would be “chicken’s egg”.
Incorrect, a “chicken’s egg” would be an egg in the possession of a chicken, which would be the egg a chicken lays. The “first chicken” did not hatch out of an egg laid by a chicken because they didn’t exist.
You’re right. I just realized that I typed the opposite of what I meant. And then in another comment said what you did thinking I was defending my og opinion. I’m all over the place this morning.
