Sex- linked Information

so do you know what colors the girls and boys legs would be?
Thank you so much for the info

What I've heard is a black skinned rooster (silkie) over a white or yellow skinned hen should give males with white or yellow, and females with black. I've not been able to test this myself yet....
 
Can anybody help me with this? I think I may have accidentally produced a Sex Linked cross. I've been learning the genetics a lot lately but I'm not 100% on this.

This is daddy, a Jubilee Orpington.

This is momma, a Silver Penciled Plymouth Rock.

And these are the 10 chicks hatched about 4 weeks back.

I got suspicious because all 3 of the Reds are looking very henny, and 6/7 silvers look very male (the last one is kinda indeterminate, but I think he may just be a small male... he's got the wattles, it's his body that's showing henny). The differences weren't completely obvious at hatch - I had multiple shades of chipmunk and a couple very yellowish birds.

Yep, that cross would produce red sexlinks. The silvers are your males, the reds are your females. Silver is dominant over any red-based color. A silver hen can only pass her silver gene to her male offspring. So all the boys would get a silver gene, and none of the girls.
 
Thanks for your help. I'm very excited, as my Jubilee male and my Rocks are probably some of my highest quality birds! Both are breeder stock, super big and healthy and seem to produce great layers and meat cockerels. I suppose I'll be setting aside a breeding pen for Benny and my 4 SPPR girls next spring then... hopefully I'll get a better pullet to cockerel ratio next time, because yikes, that's already 7 more cockerels to caponize!
 
I'm so bummed. I've apparently had a sex-link fail and don't know what happened....

Splash Ameraucana rooster over dark Cornish hen. He has pretty slate blue/grey legs, she has yellow. 10 chicks hatched, 3 with yellow legs and 7 with dark. Barn cat had a taste for yellow skin and got those three before I realized and moved them to a more secure pen. So I had 7 solid blue, dark legged birds I thought were all pullets, and I sold one a few months ago as such. Decided to keep the rest until spring for layers, and now I'm glad cause 3 of them are cockerels

. I've been in denial about them for a few weeks. Combs are small, but definite triple row pea. Legs are thicker. Today I noticed the kiss of death....a red patch coming in on an otherwise solid blue bird's wing, and in the right light the hackle feathers are shiny and darker.

I'll get pics up tomorrow for those of you who are visual like me. In the meantime, any ideas? Am I just incorrect in thinking they should have been sex linked by shank color?

Leg shank color is not linked as well as feather color.

I have been skeptical about this since hatcheries do not sex by shank color.

Don't be bummed, for years I have been breeding Single Comb RIR male with Single Comb RIW females and getting RSL's We process the males. I have also bred RIR male to Delaware females. The female chicks looked like the RIR father and the male chicks like the Delaware mothers. This past spring I put a Rose Comb RIR male with some Rose Comb RIW females. I thought they would look like the RSL chicks I have gotten with my Single Comb RIR male/Single Comb RIW females breeding with the only difference would be they would have Rose Combs. Well what a surprise. I got both white and black chicks. I thought the black chicks would be females and the white chicks would be males. One of the white chicks did turn out to be a male but all of the rest turned out to be females. I thought the only difference would be the combs. The chicks from the Rose Comb breeding did have Rose Combs. I gave away all of the chicks to a friend and kept 2 of the white chicks thinking they were males. Again it was a surprise because they turned out to be females. My friend said the chicks I gave to him were all female except one of the white chicks he took did turn out to be male. You just never know. Good luck, don't give up and have fun...







Here are some of the RSL pullets from a breeding. The pullet on the right is from the RIR/Del breeding.

I'd thought hatcheries didn't use it because you have to cross breeds and they mostly sell purebred birds. Except My Pet chicken--don't get me started on their "Fun New Just Created Breeds"

cmom, I remember your puzzling bird post. Genetics just throw us for a loop sometime, don't they?
