Sex- linked Information

[Ridgerunner]

Somewhere way back in this thread an expert said that Wheaten can be a problem in seeing the spot, but I think they may have been talking about a red barred wheaten hen with something other than an extended black rooster. In theory the Wheaten rooster should work but as you know, theory and reality are sometimes different things. I think it would work but I can’t give you any assurances.

I'd love to see your results. I'd been thinking along the same lines, but would have a harder time finding a correct male. I love blue birds, I love blue eggs, I love sex links, if I could get all three of those together I'd be thrilled. I was so upset to have to give up on the Amer x Hollands, but it was so unreliable.

Just to be clear, I'm expecting black, not blue, chicks. I like blue birds too and I have several blue egg laying blue sexlinks from last year's project. They are beautiful and lay beautiful eggs, but they were not sexable until about 2 months of age, when the hackle feathers of the males started showing the barring clearly.

My Am X BH cross worked great for the black chicks, at about 5 days, I could cull every male easily. Not perfect for selling/shipping day old's, but good enough for me since I generally sell the chicks at that stage or older.

Looking to confirm my understanding before committing to this pairing . .

I am making blue egg laying black sexlinks using California Grey pullets and Ameraucana roos. I was planning to use Black roos, but I have Wheaten Am roos from a line known for very blue eggs. I believe the EB in the pullets will express over the wheaten chick down. Can anyone think of any reason that wheaten would be a problem, or that the blacks would be better?

RIR roos have wheaten genes, right? They are used a lot with BR's for "regular" BSL's.

Last year I used Barred Hollands and Black Ams and the head spots were unreliable, I had to wait about 5 days to examine the primaries. I would love to be able to sex by the head spots at hatch, but think that is hard to predict ahead of time, so I might have to experiment with both roo colors to see if that makes any difference.

The problem with using Wheaten Ameraucana is that the wheaten chick down may be too pale to see the head spot. While most of the chicks should be black, you may get some wheaten chicks.
In what way were the head spots unreliable using Barred Hollands?

Some chicks with a head spot never developed any barring and were female. I think those with no spot were females, but I stopped paying much attention to the spot when I realized I had to keep them until they were a week old anyway to ensure I didn't cull any females.

If the CG's are homozygous for EB, wouldn't that mean all the chicks would have to be black? Does wheaten show at all when a chick is het for EB? I don't have enough experience with EB down to know for certain that it is not partially dominant, allowing some leakage of the wheaten. I've certainly seen other colors leaking on my Black and Blue Ameraucanas, especially the cockerels. I don't think that ever showed up in the chick down, however.

Am I right that a RIR is the sire used for commercial BSL's? And is a RIR homozygous for wheaten? A RIR chick looks like the wheaten pattern to me.

Hi I posted something not too long ago in Incubating and Hatching Eggs about if I crossed my buff barred Cochin bantam rooster with my blue Cochin bantam hen would I get blue barred chicks? and someone replied that I would (not full blue barred though, obviously) and they would be sex-linked and the males would be blue barred. And from my understanding I thought the hen had to be barred, not the male...So is it true that I would get sex linked chicks from that cross? Not that I'm trying to say that person was wrong, I just want a second opinion on it and to make sure that it's true.

You are correct the the hen must be barred and the cockerel non-barred to get sex-linked barring (usually called Black Sexlinks).

So the chicks would not be sex-linked then? Some of them would have the white head spot and would feather in barred, but they wouldn't be sex-linked and I'd have to wait? Not that I'm complaining. I'm fine with waiting, I'm just trying to confirm my thoughts..

I think you were misinformed . A barred rooster with 2 barring genes will produce single barred chicks with a non barred hen . So no way to tell single barred males from the normal hemizygous female chicks . As for the buff ( gold ) it is sex linked and only the females will inherit the gold from the male but mixed with blue/black they may show some gold in the down . Males will not have any sex linked gold . You would get both blue and black from the blue hen . So they maybe sexable if the females show some gold .

Wait so what color chicks could I get, and how can I tell if they are sexable and how do I sex them if they are.....I'm sorry but all this stuff is confusing to me...I get the 'cross a barred hen and a red rooster(or any color besides barred) to get black sexlinks' and 'cross a red rooster and a silver hen to get red sexlinks' but that's about as far as my knowledge goes on sex-links...
