Sex- linked Information

[lazy gardener]

I'm confused. I just went back over the charts. I was under the impression that a black sex link could be produced with a RIR roo x SLW hen. Apparently, I'm wrong?? Last year, I got some nice sex links with EE roo (lots of red coloring) over PBR. Am expecting to have some more black sex links using one of the sons of that roo (full EE, no PBR in his genes) with my Dominique hens. I know that the mixed parentage of the EE can produce some surprises, and I'm ok with that. But, assuming that he throws chicks, and his genes work like a RIR, what would come from him with SLW hen? Red sex links?

Also, I'll be breeding the EE roo to his half sister black sex links. I know they'll be a barn yard mix. But, any idea if I'll see any barred birds come out of that breeding?

RIR over SLW gets me Red Sex Links. Red Hens with some incomplete lacing and mostly white roosters with colmbian pattern black markings on the neck and tail, some of the males have very a little bit of incomplete lacing. When mature they have a yellowish tinge to their hackles and coverts. You'll get no barred birds from the BSL girls the only Barred gene their mamas had went to their brothers along with the male Chromosome.

Just curious, is your EE Black breasted? or red columbian? or some other pattern? I wonder if you'll see a little more lacing than with a RIR.

Fun cross..  and yes.    I'd like to see pictures of this haha

Okay, I will take pictures and send them to you. Also, will a golden laced polish roo over a silver laced polish hen make a red sex link?

Yes good question.

If using the silver gene in the hens with no barring, it is absolutely important for the roosters to be pure for gold.. not silver or half silver/half gold. "lots of red coloring" is still vague as some silver or especially half silvers still manage to get a fair bit of red/gold pigmenation.

Thanks! and you are on the right track of red/gold rooster over a silver hen for sex linkage.

However, just in case- a buff lace roo over silver hen would not work because buff laces have dominant white and that will turn all chicks and birds an off white color all over and thus masking all traces of sex linking.

Kev, I thought dominant white basically just turned black feathers white and did not have much (if any) effect on red. Some of the red sex link pullets some hatcheries sell have white tails because of dominant white.

As long as you don’t have Extended Black in the mix, it’ possible to create a red sex link even with dominant white. Birchen may be possible but it’s trickier because the areas that could be red or yellow are more restricted.

How sure are you that a buff laced actually has dominant white? Using the calculator, I get a white patterned buff laced with Dominant White and a black pattern buff laced with black wild-type (Non-Dominant White). I just add Mahogany and Dilute to Gold Laced.

Will try to post a pic.

Thanks, for the info on both counts.

My rooster does not have any black on his breast. He looks very much like a RIR roo. But he has a wonky pea comb. As I said, I'm hoping that he will give me sex links, but, won't be overly upset if he doesn't. His Daddy gave me some nice sex links. They're solid black, no red bleeding at this age. (they're 11 months old) They have very tight pea combs, and lay a nice large dark blue/green egg.


Jack, the roo in the fore ground. One of his 1/2 sister BSL in the back ground. I don't have a pic of him showing his breast.

I just figured out how to change my avatar. While that avatar pic is not as clear, it does show his chest a bit better. He's a nice boy, maybe not so much for his conformation, but he's a sketch, and adds a lot of personality to the flock.

Buff lace is gold lace with dominant white. For the very reason you mention about DW affecting black while leaving gold pigments mostly unaffected. Remove dominant white from a buff lace and you will be looking at a gold lace.

I've done crosses with buff lace. all proved this idea. Crosses with WCB produced the classic cream chicks with random black spots just like with white leghorn crosses. They grew up into off white all over birds

I just realized I made a mistake with the comment about buff lace over silver lace..... the males would turn out off white all over, due to combination of DW plus silver lace basically cancelling out the pattern. The females should come out buff laced.
