Pleae educate me! My understanding is that you need a rooster w/ the "brown gene" and a hen w/ the "blue gene". Yes? I have found two locals who are crossing an EE with a Wellsummer and getting olive colored eggs. Which brings me to my next question - once that roo & hen mate, are the eggs she lays going to be olive or do you have to wait for the eggs that that original offspring lays to get the olive eggs? And the eggs of a hen resulting from an olive egg will always be olive? And... Which roosters carry the brown egg gene? I was hoping to use a French Black Copper Maran rooster with an Ameraucana. Will this combo work (to the best of your guesstimation)?
