Thank you all! I discovered that only two of the big hens are laying. Godzilla for sure lays the brown egg. They keep getting prettier and prettier. A very pink, rich brown with little speckles. I haven't caught the white egg layer but I believe it is Lady. Also, I set eight eggs in the incubator on Saturday, so hopefully all goes well!
It's possible that Godzilla is an EE/Marans cross. You might try looking for a Marans roo for her, because their babies would lay lovely dark brown eggs, possibly with that rosy/plum hue.
