Black To White Experiment

[MysteryChicken]

I recently read an article about egg colors, they can exhibit partial dominance so some colors may actually mix with others, the primary colors that are mixed are back, white, red, blue, and yellow. Most of the time the the red yellow and black are mixed, so dark orange that ends up "brown", but sometimes one or the other can express more, or get mixed with the other colors. This is how we get pink, chocolate, or green eggs. The blue of course is often in the undershell/mixed into the enamel, but the blue enamel could be only mildly present with the brown pigment over the top, so the end result is a mild green that looks beige in lower light, they have charts for predicting egg color from various crosses. I found it fun, was considering breeding an Aracona into my flock to see if I could get the cream dorking eggs to get blue enamel and turn baby blue.

There's only White, Brown, & Blue that exists. I've read something about gray eggs, a separate mutation, not green with thick bloom, but I have no idea what that looks like.

Okay, her second egg I cracked it open, removed the membranes, it's blue tinted this time.
Now I'm wondering if she just had a glitch since she's a new layer. Still odd the eggs appear a normal tinted egg color in natural light though.

Beige mixed with blue, try to find the beige? Hint there's 2, one above the other.

Do you mean, 2 beige eggs and some number of blue eggs in the basket?
Or do you mean, 2 eggs have both beige & blue in their coloring, and the others are just blue or just not-blue?

I see parts of 16 eggs in the basket.
It looks like they are roughly sorted to have the blue/green ones to the right side and the other ones to the left side (the ones I would call "some shade of brown.")

I think either 9 or 10 of the eggs have some blue (not quite sure about one that's buried in the middle, because it could be reflecting blue from the eggs nearby rather than actually having that color itself.)

There are two near the upper left, both with very dark dots on them (dirt? poop? impressively dark speckles?) that I do not think have blue, but if I were there in person I would be looking at them in other lighting before deciding for sure.

If the article is online, can you provide a link? That does not match what I have read elsewhere about chicken egg colors.

The eggs at the front of the basket where there's only the blue eggs. The cream, & tinted in the back I tried to avoid in the picture.

But I just came back, & updated.
