Then the mother should not be a Marans or an Easter Egger.
So the mother is Rhode Island Red, or Gold Laced Wyandotte, or something not listed.
Do you know which rooster breeds were in the flock?
If they just have to be on that list, the father would be Black Copper Marans, or Easter Egger, or Rhode Isladn Red, or Gold Laced Wyandotte, or something not on the list you posted.
But the chick is not a pure Rhode Island Red, and it is not a pure Gold Laced Wyandotte, and I'm pretty sure it is not a cross of those two breeds either.
I'm strongly suspecting there is some breed in the chick that wasn't on the list, but certain kinds of Easter Eggers could also account for the traits of the chick. Easter Egger could be the father, or else the mother could be an Easter Egger that laid cream eggs instead of the blue/green she was supposed to.
