Is that true? You can get a blue egg layer by crossing a white with a green? I have three white layers, three green layers and a olive. But my roo is a brown :-(
Green eggs is from a blue shell with brown pigment overlay... crossing in a white egg layer dilutes the brown pigment... as long as the blue shell gets passed to offspring, it *should* produce more blue rather than green... works best with double blue shell genes, but can be done with single...
