    I just hatched some Olive Eggers (Ameraucana x Marans, variety of generations and back crosses) and don't have any interest in keeping ones who will end up laying brown eggs. I read that in Ameraucana based Olive Eggers, if they have a pea comb then they also have the blue egg gene. Is this true 100% of the time? I wouldn't want to prematurely get rid of anyone based on comb type!

    I would not bet any money on it. Egg genes and comb genes are two entirely different things.

    Agreed. I have both single and pea combed chickens that lay blue and green eggs.

    That's interesting, are they Ameraucana crosses or from a single combed blue layer? The explanations I'd read were that while they are obviously different genes, in Ameraucanas they are very closely linked so it's unlikely for the offspring to inherit one without the other. But even if that is accurate, I've got no idea how the varying generations and back crosses may change things :idunno

    They are not linked. They both just happen to be dominant genes meaning that it only takes the presence of one copy of the gene for the trait to be displayed.

    They are mixes of mixes. I live in South America - Brazil - and it is very hard to find purebreds (of any breed).

    Here's one of my hens, single combed and lays beautiful blue eggs. I am currently doing some breeding for egg color, one of her daughters is pea combed and lays very nice blue eggs as well.
