Hello I would like to breed for Olive Easter Eggers. I have Purebred Black Ameraucanas, Blue Marans and Welsummers. I would like to cross my Ameraucana with my Marans and Wesummers. The Ameraucana has the dominant Blue egg gene, which i believe I can represent in the phenotype OO, if the brown egg is recessive, I can represent it as brbr. If I cross the phenotypes, I get all Obr, so all female offspring should have green eggs. I have read that if you breed Olive Eggers, some may lay blue eggs, brown eggs or the desired olive green eggs, you won't know, but how is that possible if the brown egg is recessive to the blue egg? If I want to sell Olive Easter Eggers, if the latter is true, then my concern is that I can't guarantee Olive Egger pullets. Can someone with a clear understanding of genetics clarify this for me. It's been ages since I took genetics in school Thank you so much.
