Marans Thread for Posting Pics of Your Eggs, Chicks and Chickens

[Dread Pirate Roberts]

hey youz guyz...I've a question about making Blue Sex Linked Marans...

I actually have another thread in this forum on BluSL, but as is often the case with BYC, it's gotten all clogged-up with garbage and nonsense. One of my pet peeves is when people without a comprehension of science make silly statements on topics which require a rudimentary comprehension of scientifical things. Since this is probably the singlemost thread regularly viewed by people knowledgeable on scientifical things, here's muh question...

Given the rules of Blue Andalusian Genetics:

If you breed any of the following ways this is what you'll get:
Blue x Blue = 50% blue 25% black 25% splash
Blue x Black = 50% blue 50% black
Blue x splash = 50% blue 50% splash
Black x black = 100% black
Splash x splash = 100% splash
Black x splash =100% Blue

How would I make BluSL Marans?

For the purpose of applying the barred/sex-link rule to blueness, do we consider barred to be "black"? And thus use a splash roo over barred (cuckoo) hens to get 100% BluSL?

Thanks!

Blue is not sex linked. There is no way to manipulate the Blue Andalusian gene to indicate the sex of a chick by the plumage. Wish I could tell you what you wanted to hear, but "you can't get there from here" or something like that. Sorry your other thread got clogged up. St. Helena is a GORGEOUS town. Lived up near there in '79

Thanks, Patty! You are exactly one of the "scientifically minded" people I had in mind!

Did you see my other thread? https://www.backyardchickens.com/forum/viewtopic.php?id=295139

Does it clarify what I'm trying to ask? You see how I'm thinking Blue X Barred? Or Splash X Barred?

Dread Pirate Roberts, I read your other thread, and just thought I could add something. You could force Andalusian Blue into a sex linked equation so that the resulting offpsring were both blue based AND sex linked, but they would not be sex linked because they were blue, they would be blue because you forced it with splash over non-andalusian blue carrying mate, and overlaid some sex-linked trait properly applied... make sense?

Yes, they are considered a genetically black bird.
Splash roo over a cuckoo hen = heterozygous cuckoo males with one copy of the barred gene. All sons from this cross should be blue cuckoo and all daughters should be solid blue. A cuckoo hen can only give the barring gene to her male offspring.
