I hatched four pullets from green eggs. One laid green eggs, the others laid pinkish eggs, not blue or green. The fathers were not EE's, so this just means the mothers only had one blue egg gene, not two. If the father had also been an EE, my chances of getting more green or blue egg layers would have gone way up.
If you crack a green egg, the shell underneath is blue. That is genetic. The basic egg shell color is what it will be. That will not change. You get the differnet shades of blue or green depending on how much brown color the hen puts on top of the blue.
