No doubt... but doesn't appear to be the problem here. These are great eggs... right up to the point where they die. It's gotta be bacteria in the incubator. Hen is fine. Diet is great, nutrition is as good as I can get it, and she is maintaining weight well.
No, this is not correct. They can by homozygous for the color -- not split -- and still be white. The genes are not alleles, except for white and pied. White is not an allele for blue.
Exactly. My own wild theory (because I haven't heard anyone say this is correct yet) is that the Black Shoulder gene interferes with laying down some version of the brown pigment, leaving the feather with just the base color for that area. I think that could also explain why the BS hens are so...
My thought with this whole "hiding" thing in terms of "silver pied gene" is that it goes back to a concept that some folks keep dragging up... that there is A silver pied gene, which isn't generally thought to be true. Some of the genes involved in silver pied may not be expressed, or may...
Well if, to have silver pied, it requires that a bird carry one pied gene, one white gene (both alleles) and two WE genes (homozygous for WE), then the "dark pied bird from silver pied parents" is not exactly "hiding" silver pied genetics. It just happened to get two pied genes (one from each...
