Here is a great picture I found in the Journal of Heredity!

There are three Chicken breeds that lay blue eggs: Ameraucanas, Araucanas and Cream Legbars. The blue color is created by oocyanin, which is applied early in the laying process. The blue pigment goes right through the shell, unlike the brown pigment. So blue eggs are blue inside and out.

I have heard of certain recessive strains of Coturnix can lay white eggs and even some blue eggs. I have even heard of light green eggs in Coturnix quail too.

Interesting stuff!
 
So we just put in a batch of Celadon Blue Quail Eggs from James Marie Farms in our GQF 1500 Professional.
The humidity reads 54% and the racks will auto turn.



I wonder whats going to pop out in the next 17 days....
 
Very interesting! Keep us posted on the chicks when they hatch

The celadon egg mutation currently doesnt 'stick'to any specific genetic material so dont be dishearthened if your offspring dont produce celadon eggs. It will currently crop up at random often skipping generations.
 
I'm suspecting this gene for blue eggs in coturnix is actually more of multiple genes that inhibit the application of beige, tan and brown egg coatings. Most of my quail lay blue or green eggs when you look at them from the inside. Check out this plate of egg shells from hard boiled cot eggs, most of them are blue and green inside! (Sorry for the lighting, my flash wasn't working)


So my theory is these celadon eggs are from hens that don't put the coatings over their blue egg shells. This would explain why the trait is so hard to breed for, it's not a single gene that quail have to put color on their eggs.
