Anyone have info on Olive Eggers

Here is a graphic I found on this site;

May help with your question on what and F1 + F1 will or can do.

Pretty much what I said only sure is easier to understand looking at chart.Only thing I would argue is you don't always get Olive egg when you cross dark brown and blue layers.

Mother nature has her way of doing things contrary to our thoughts,,, and the chart leaves out white eggers.
I have a hen that should have been an OE, she lays a brown egg with a purple hue. Her chicks lay blue, green, brown and pink.

The chart is colorful and pretty but not correct.

Welp - that's unfortunate. Do you have an accurate one? Or... If you could give me the actual alleles and how they're inherited I could try to make a chart myself.

New to chickens, but genetics is something I love~

I thought you and @lomine were covering it pretty well.
First part is mostly correct. Blue egg Xs brown egg = green egg. Of course light brown = lighter green and darker brown = darker green but you cant be certain a dark brown will = olive.
You can cross a dark brown with a blue and get various shades of green. So I don't like how the chart makes it look like all the eggs will be the same olive green.
After the first cross the chart is useless. As you know olive Xs dark brown will give some different shades of green and also various brown egg shades.
Same with olive Xs blue. You won't get just spearment eggs.
Of course you know this so not much help.
With egg color in olive egger projects its hardly ever A + B = C

If your OE are first generation that means they all carry one blue egg gene and one white egg gene (brown egg is brown coating over white egg). That means each offspring has a 50% at one blue/one white, 25% chance at two blue, and a 25% chance at two white. The blue egg gene is dominate so if a hen has at least one she will lay a blue egg. Two white egg genes means no blue or green eggs. The genes for brown coating are a little more complicated (and outside my basic knowledge of genetics) but you'll get a majority of green eggs but there also a pretty big chance of just brown eggs.

Your EE rooster may be pure for blue eggs (two blue egg genes) or he could have one blue/one white. There's also a chance he doesn't carry the blue egg gene at all. Unless you want to do a DNA test, the only way to test would be to breed him to a white layer. If all his daughters lay blue eggs he is likely pure. If some lay blue and some white he carries a one egg gene. If none lay blue he has two white. He may also have genes from brown coatings. I'm not sure how that would play with the dark coating of the OE, it might dilute the darker color and give lighter eggs.

If your OE are not first generation, then you'll have to breed them to figure out what they carry.

I want to try to breed my EE male as he really pretty. but so is my OE lol. I plan to try to breed them see what they have. As in the OE
Now can I breed dad back to his hens for a line breed? I know I can do line breeding in mice/rats bunnies and guinea pigs have to be more careful with but not sure about chickens. I just kept them as pets let them breed on their own and only ever had a few hens brood but only ever had a hen and a duck hatch some out lol.

See in my head if you breed and Olive with another Olive that would still make it and olive just not certain on egg color. if you breed them together since they are both Olive Eggers. but if that is not right then what would the offspring be called? lol. that is like saying to me breed 2 golden retrievers together but not get a littler of goldens.. lol I know chicken breeding is different by a lot then dogs but i am talking about if you call something this breed (even a cross breed to make it) breeding the 2 together makes more even if its a new generation of what it was. hope you got that lol. So would the chicks from 2 olive eggers still be olive eggers? just eggs will not or maynot be green?

You can line breed if you want. That's what breeders have to do if they have mutations pop up and they want to expand on them. That's how the Welsh Harlequin breed was created. They were originally a mutation in Khaki Campbell.

I love genetics to and am trying to get a handle on chickens and ducks. lol I know mice/rats guinea pigs and bunnies its been a while.. but even in the rosdents I still learn new things. I just like to read it sometimes in more laymans terms and like chars and pictures as it gets in my head better.
