Weird Egg, Chicken or Duck?

[Blue Andalusian]

This Morning, i went into the Coop to go feed the Chickens and pick eggs. And noticed this Funny looking Grey egg, with spots and scratches on the ground. It was almost the Color and Pattern of a Dappled Grey, We have ducks in our coop. 6 of them, 2 are only Females Though. And my Mom thought it was a Duck Egg, but it looks too small to be a Duck egg. If someone could tell me if this is a Chicken or Duck egg (Although, I think its a Chicken. Just to make sure), as well as If they'res something I need to do (Give the Flock more Vitamins, etc...). That'd be Great, Our Ducks hatched in June 2024. If anyone wondering

Could it be from a newer layer duck? I'd crack it open and see as you should be able to tell as duck egg yolks are darker orange than a chicken's yolk.

Thank you! We will, we just got another egg this morning too. Both times it was found on the Ground
