Sex- linked Information

No on the barred. They would act as silver for a red sexlink cross though.

Hamburgs will not work as the female side (silver) because they carry the birchen gene. The chicks will be a black backed phenotype.

Black Coppers will not work on the male side ( red sex linked) because they carry birchen.

Birds that carry the birchen allele will not work as the male or female in a red sex linked cross.

As a general rule, do not use birds that are spangled ( appenzeller, hamburg, etc.) or autosomal barred ( campine, fayoumi , etc.) or laced polish in a red sex linked cross. I am going to have to go back and put some do not use in the article.

I wrote the article on how to make a red sex linked not how not to make a red sex linked fowl.

I wrote the article to help prevent the questions but it seems as though it has not worked.

I found it very helpful. Being a chemistry graduate student doesn't hurt. Genetics is complex and people either understand the concepts or they don't. I imagine not knowing the particular genetics of a certain breed makes it challenging (for example, I know very little about chicken genetics, so had no idea that BCM carry the wheaten gene; a plymouth rock or orpington person may also know next to nothing about BCM).

However, I see a lot of "I have this chicken and this chicken what will I make" posts as though there is a magic chicken fairy somewhere in the cyberwebs. The easy answer, of course, is "no it's not a sex link and no matter what it's a mutt"...

Loved the article! Thanks for sharing! It's not your responsibility to ensure that people understand it. You did a great job!

Hello!

I have a sweet mutt hen that looks exactly like a barred rock, except with a pea comb. Her father was striped and her mother was a green egger.

I have 3 very nice BCM's one dark, one medium, one light.

If I put my mutt striped hen with a BCM will the offspring be black sex linked? Should I choose the darkest BCM or does it not matter?

Is it a risk because she is not full bred? Is it a risk because BCM's can be birchen?

thanks!
Renee

Yep, it will work, if she is indeed barred like a barred rock, she will work for making sexlinks. The barring gene works the same regardless if its on pure hen or a mutt hen. And a BCM roo will work too for a black sexlinked cross. Carrying Barring and/or Dominant white are about the only disqualifications that prevent a roo from being able to make black sexlink offspring. His birchen base wont matter for a black sexlink cross but as takerson said, a BCM roo shouldnt be used in a red sexlink cross, though the sexlinkage would still come into play when using a BCM roo for a red sexlink cross since he is gold gened, by the problem is that since the chicks will be mostly if not solid black at hatch, they wont be able to be sexed until the gold hackle coloring starts coming in on the pullets after they feather out and the silverish hackle coloring on the roos, and at this point, they will alreay be showing visual sex difference signs like comb size and such, so thats why a BCM roo wont be effective for producing chicks that are are sexable at hatch in a red sexlink cross, but they will work in a black sexlink cross when paired with barred hens.

I agree Tim, since there are countless possibilities on HOW to make sexlinks, it would probably be easier to do a "What NOT To Use" list.

ohh kk. i crossed a Partridge Penedesenca roo with my california grey hen. and the babies look like this. i was wondering if they are sex linked. some eggs didnt hatch. and i opend then and some were black with white on there wings and had white feet. but the ones that hatched looked ,ike this. some people told me they are sex linked. some told me they arnt. u seem to know more about sex linked chickens. soo what do u think

goin back to this question i asked a while back. all chicks i hatched looked like the one in the pic. and sooo far the ones i can tell gender on are pullets and the new chicks i did feather sexing and they seem to be pullets. did i get lucky and just get all girls?? all 5 eggs i put in the bator hatched. i gave two older ones away someone wants to put with there cockrel. i still have 3. hopfully they all turn out girls and that mating these two breeds did infact make a black sex link. ill post a pic of the oldest chick and maybe u guys can tell me black sex link or not

Yep, those should be Black sexlinks and it is possible that you got only females, especially with a small number. The hens are supposed to be the ones that determine the sex of the offspring in birds, but at one point I was using a buff orp roo on barred rock hens to make black sexlings and was getting about half and half of both sexes, the I switched to a RIR roo on the same hens and I only hatched a few at a time and only a few times with that roo, but all the ones I did hatch were females.

its intresting how u can make sex linked chickens. i didnt even know breeding the two breeds i bred together wold make sex links till after they hatched lol

here are the most recent pics of the oldest two i still have.

this ones about two months old

this ones about a month old

thanks very much clint!

Can Silkies be used in sex linked crosses? Like a Blue Silkie over a Barred Rock hen? Would they produce sex linked offspring?
