Hi! I have 2 silkie-feathered green-egger hens --- they both are blue and lay pale blue-green eggs. They are in with my Silkies (splash roo and white roo).
The 2 pullets I kept (a blue and a splash) look pretty good, but aren't quite ready to start laying yet.
If you want to try some eggs, just let me know.
I don't know if blue would mess up your whites, but they are available.
I also have Naked Neck green-eggers, NN Frizzled green-eggers, NN silkie-feathered green-eggers.
Patti (RubberChickenLubber) just hatched some of them recently (video of hatchlings, I don't know if she has updated pics).
