Egg color question

I know “Facebook” isn’t a good answer

Yeah, it's not.

how much the two platforms mistrust each other is hilarious! Have you ever seen how they say the exact same about BYC info there?
Well, if I must, I will reference @nicalandia ’s post.

However, pea combs are closely linked to the blue pigment producing gene,

While it may seem like pea combs are linked to the blue egg gene, they are not. It just happens that both genes are dominant genes and only need one copy of the gene to cause the trait to be displayed. You can check Brahmas and Cornish and other pea comb breeds that do not lay brown or green eggs to see that there is no link between the pea comb gene and the blue egg gene.

They're not linked, as such, but the genes are close together on the chromosome. During meiosis, when the chromosomes recombine, the chromosome is unlikely to break between those two genes because they're so close together. Because of this, if the chick inherits one, he (or she) is very likely to have inherited the other.

Both of my sapphire girls have crests, and one still lays a brown egg.

Today, our daughter got her first green egg!!! So yay--at least one of them is a greenie!

It's not a BYC vs FB kind of thing.
Both platforms can be rife with misinformation.
It boils down to the individuals in either place and how they cite their sources.

Here's the lighter lady's earlobe. I had a hard time getting the camera to pick up the slight teal coloration, but it's the best I could do with the lighting. She's the one who laid the lovely green egg today!

Definitely from Crested Cream Legbar stock.
That opalescent(blue tinged) white may fade...did on my CCL's.
