I read on other posts that single comb will seldom lay blue/green eggs. So it would be correct to assume single comb EE roo 's do not carry blue genes? Now if you breed a sinlge comb EE (lets assume no blue gene) to a green egg laying hen, do normal mendellian genetics apply? For example if she was homozygous for blue, all hens would lay green, if she was hetero for blue, 50% would have the blue gene 50% would not? or is it more complicated than that?
