I thought i was refering to how you get nice olive eggs like the picture above. The darker the egg(marans) crossed to a blue egg gets nice dark olive. I wasnt refering to the way a pullet looks.
The darker the egg like a marans egg with a blue egg layer gets the best olive color. Im not sure but i think you need a blue egg breed roo over a dark egg laying hens(marans) for eggs like that
