Sex Linked Olive Eggers?

[Brahma Chicken5000]

I wonder, if I find a good cross that produces good Olive Eggs, and I like the colors, (I might try several crosses,see what I like, see how the eggs turn out).this may be super complicated, and may not even be possible, but is there a way to find a cross, and have them breed true? Would you need to add more in, etc? I think it would be neat if you could produce a auto sexing olive Egger that bred true. Thoughts?

It might be possible if you used cream legbars as the parent stock and bred them to a brown egg laying hen and then back crossed the offspring to cream legbars for a couple generations to get the legbar look back.
Side point-If there is no green egg gene and the only way to get green eggs is to breed a chicken with the blue egg gene to a chicken with a brown egg gene. What egg gene will the offspring carry? What if there was a way to link the brown egg gene to the F1 Olive Egger males and link the blue egg gene to the F1 Olive Egger females, that would be a way to create F2 Olive Eggers females that would lay Olive eggs and carry the blue egg gene. I hope I’m making sense.

Wild type is recessive to Wheaton. HERE are some photos of e+/eWh chicks from the Rhodebar thread. There can be a lot of leakage of recessive color patterns through dominant color patterns. There are three wild type x Wheaton chicks in the photo. Two of them came out with stripes (although not sharp in distinction) and one came out with out any stripes at all. When you get into "theory" on hybrids the plans is not always fool proof. Even in "pure" breeds their is a lot of variation do to the complexity of genetics. Line breeding reduces a lot of variation and brings uniformity. With out limiting the gene pool through line breeding there are lots of surprises. You also may want to scroll up from the photos to post 1112. It list many of the results from different crosses of barred birds with different color patterns.

You are correct. Wheaten is dominate to wild type. At least if you go by the book it is.
Sometimes I get confused. Need to do more reading then breeding I guess. I think the problem is that wheaten didn't read the rules either.
Just like you example pics. Three chicks were produced. Two look close to wild type and one wheaten. If wheaten is dominate why the majority of offspring hatched looking wild type? Doesn't seem wheaten is dominate or all chicks would look wheaten, right?
I've done the cross myself and only got wild type chicks. When those chicks were crossed I got a few wheaten and also a majority of wild type.
In my experience wheaten sure acts recessive to wild type. Some did have a lighter pattern so wheaten did have an influence just not what it should of had.
From my experience is why I said it wouldn't be my first choice because of the unsure outcome. In the pics you linked a head spot would show well on two of the chicks but not the third.
I will give you that I misspoke about the wild type being dominate. Many sources agree I was incorrect but many that have done the cross also don't get the expected outcome just as I never had.

What breeds and varieties do you or could you have that lays dark brown eggs? And blue eggs?
Also subjective to your opinion on what pretty is.
I don't think it is super difficult to mix patterns then breed for a couple generations and get to auto sexing.
Its just a matter of figuring out what you want and if you have access to birds with the right patterns to get there.
There's several patterns that can be auto sexing but it is limited to what can work.
Legbars are kinda the go to pattern. Of course barring is first and best is a good dark chipmunk chick down pattern.
You quickest easiest route would be crossing a male legbar to female welsummer. The F1 pullets will be auto sexing. Cockerels will be half way there and the cross will be olive or at least green egg layers.
See what the pullets lay. If they lay a dark green/olive egg breed them back to a legbar male. You'll then have all offspring being auto sexing. You will still have some genes to work out or in. Such as the cream gene and crest genes from the legbar.
If your F1s lay a lighter green egg you can breed F1s together and get about half pullets that are barred and auto sexing and half cockerels that are double barred and auto sexing.
Or you could breed the F1 cockerels to welsummer pullets and still end up with half the pullets auto sexing and half cockerels with one barring gene so you'd have to get a second barring gene back to them.
Your issue as always with OEs is keeping the blue egg gene and the dark brown genes in the same bird. The crosses by nature is going to keep bringing in white egg genes. You have to keep breeding to get the blue egg gene to continue on and in a perfect world get birds that carry two blue egg genes.
Problem is every cross to bring in the blue egg gene is breeding away from the dark brown genes. Then when crossing to bring in the darkest brown genes you need it is breeding away from the blue egg gene.
That's the issue with long term OE projects.

Wow! Thank you so much!
I really don't exactly care what they look like.
I wonder, could you use Marans instead of the Welsumers?
Also, I may just be mixed up, but I thought is was barred hen x solid rooster, for the sex linking? Not barred rooster to solid female? Sorry if I'm being a Bother, but I really appreciate your time in telling me all this!

You can use marans. Only thing is marans don't come in much for color. Pretty much black, blue and black and blue copper.
Solid rooster Xs barred hen is sex linked.
Barred hen and double barred rooster for auto sexing.
Auto sexing is best with chipmunk striped chicks which is what welsummers are.
Marans don't come in chipmunk stripe chicks so for auto sexing it would take another generation and hatching more chicks to get the right pattern.

I have done what you are describing with Black Copper Marans and Cream Legbars. Below shows the results of the eggs. The chicks all hatched black. The males have a white spot on their head and the females don't.View attachment 1256406

You have?! That’s exactly what i want to do!!!! Have you got any pictures?

The pullets show are the result of crossing a BCM roo with a CCL hen. The olive eggs shown are the result. Interestingly both pullets decided to lay on the same day. Eggs shown with mother's egg (blue) and another BCM egg for interest. The olive eggs go through interesting color changes as the hens get further into the laying cycle. These girls have laid a pale green through to a deep olive drab.

Wow, thank you, they look very nice. Sorry to bother you more, but do you happen to have any pics of the chicks, or any roos?

 

[oregonkat]

Top pic is of the male chick (white spot)
Second: Pullet
Third: Cockerel
Fourth: Cockerel at about 2 months I think. I did not keep any of the cocks although I am regretting that decision now.
