The Olive-Egger thread!

? Will an isbar rooster crossed with a maran hen result in olive eggers? Also the other hens are comets, buff orpintons and Javas would these end up being Easter eggers? I'm pretty sure this would be the case but I'm just checking. Thanks so much!!

It gets to be a bit more complicated when you are not using Ameraucana(Standard of Perfection type). isbars and cream legbars are not EEs so they would be isbar crosses.

isbar x marans will make OEs but some of them will lay brown eggs if the isbar is not double blue for egg shell gene.

OK. I wasn't sure found some eggs local I could hatch. And thought maybe I got lucky. Would the is bars crossed with the other brown layers create a unique colored egg? I've read that the is bars egg color is due to the color of the blume. Is this correct? If so is it worth hatching them to see if maybe there could be some pretty colored egg layers from them?

The egg shell is either blue or white. That is determined by two genes. Blue is dominant so it only takes one white to make the shell blue. White is two recessives.

Brown is 9 to 12 genes and the number and type determine the darkness of brown. Bloom is added after the brown is deposited on the egg and it is usually clear. Langshans and a couple of other breeds have a bloom that will make the egg look reddish so those eggs will be lavender on dark brown eggs with white shell. They will be rose colored on light brown or not brown white shelled eggs.

A blue egg shell with a brown coat makes a green egg. The darker the brown the closer to olive colored the egg will be.

Some eggs even get to gray in color.
 
Ok, I am new to this but how do you know if your Isbars are double blue for eggshell jean?
I have heard of a person that does genetic testing but they may have stopped.

Breeding them will tell--if you get some with white shells than they are not double blue for egg shells.

It is quite tedious. Most isbars will be double blue though. The second generation away will not be though.

Here is a couple pics of my olive eggs and a couple of blue copper Marans for contrast . I have a few more girls that should start laying soon.
