Ok everyone tell me what you think... I have a black maran rooster that I bred with my brown EE hens, they (hens) lay blue and green eggs. I have a white rock hen that was broody and hatched five out of six eggs. 1 was not fertile and one chick didnt make it so I now have 2 blacks and 2 silver grey chicks. I was told that a maran rooster crossed with a EE will cause the chicks when grown to lay a dark olive egg? Is this true? Any input will be greatful! Thanks Sam
