I candled all the eggs I have in incubator and under hen, all were fertile from other sources but 2 eggs I had from my chickens were not. 14 eggs on their way...

England has easy access to cream legbars. Cross with Marans and you will have olive eggers!
For the most part yes, but you will have a chance of the blue egg shell gene not being present--some of the eggs will be dark brown and not green.
Blue is dominant but the first cross will make the OE hens lose one blue egg shell gene. The next generation back to dark brown will introduce only a white gene from the dark egg layer, so you can get two recessive white egg shell genes.
