Sex- linked Information

[cmom]

Thanks for the comments so far. I had read that I could use Delaware hens to make sex-linked crosses, but was not sure if a Delaware rooster could be used for anything. Maybe I will reconsider my Delaware rooster and match my Delaware hens with a diiferent breed rooster to make red sex-linked.

I did an experiment a few year back with Rhode Island Reds and Delawares. A RIR male with Delaware female, the male chicks look like the Del females and the female Chicks like the RIR male. A Delaware male with RIR females and all of the chicks looked like the Del male.

I have both Single Comb Rhode Island Reds and Rhode Island Whites. I have created Red Sex-Links by using an Rhode Island Red male and Rhode Island White females. Some of the males here are RIW and RSL. These boys went to freezer camp

His is one of the young males and females from the RIR/RIW cross.

I kept 2 males and the females for another breeding experiment.


I also have Rose Comb Rhode Island Reds and Rose Comb Rhode Island Whites. I did a cross using a RC RIR male with RC RIW females. The female chicks came out black and the male chicks white. Totally unexpected. I did this experiment 4 times and each had the same results.

Cmom that’s what we are talking about. Obviously you have black hiding under that white on some of your birds. For that to happen it is either only on some of yours or it is split. Sometimes you get barring. You just don’t know what might be hiding under there.

It looks like you got three black females if I’m reading your picture right. I don’t know of any sex linked reason they would all be females, probably just coincidence. It may not always work but it’s sure fun to try this stuff, isn’t it?

Yes, With the Single Combs I get lovely RSL's, but for whatever reason the Rose Combs are different. I just wanted to experiment. I did some others in the past with RSL's 2nd,3rd and 4th generations. The white or silver gene was the dominant gene and with each new generation more and more of the birds were white.

Not sex linked, but a fun trait showing up in my barn yard mixes: I was having a hard time figuring out which chicks came from which hens. But, a lot of them are now presenting with white ear lobes. (I have 3 RCBL hens in my flock.) Nice distinguishing feature. But, if these chicks produce what I expect from them, they'll lay blue eggs!

Yes, for the first cross, but the barred parent MUST be the hen, in reverse the white spots (barring) will be more or less evenly split between the sexes.

So would this same hold true if using a Norwegian Jaerhon roo over a solid hen? That's the way I understood it, but I have 2 NJ roo chicks and no hens so was trying to come up with a productive way to use the boys if I don't get my hands on some NJ girls. I love the breed and want to keep them around..if anything, they would make a good pairing with my layers for some great laying chick's but nothing beats being able to sex chicks at hatch..lol

Will the above Ro be black enough to produce sex-linked chicks breed with Barred Rock or California Gray Hens? He is a F2 Oliver Egger. Black Copper Marans over Ameraucana. (Not EE)

Most definitely!

Btw if the Grays have the Bsd gene- sex linked dilution, it is like cuckoo but much lighter you will be able to create an autosexing line. The cockerels come out very visibly lighter than pullets right from hatch and as adults the cockerels are nearly solid white while the hens are light colored cuckoo.

I hope you are not looking for colored eggers out of him as he has a single comb... most likely does not have the O gene for the colored eggshells.

This only happened with the Rose Comb RIR male with the Rose Comb RIW females. My Single Comb RIR male with my Single Comb RIW girls made Red Sex-Links.

I've been reading about sex linking by down color, but I haven't read any posts discussing sex linking by leg color. It is possible to use roosters with dominate feather color to make sex links if they have recessive leg color to the hens dominant leg color. If your sexlinked hens have white legs you can breed a yellow leg rooster and get another generation of sexlinked offspring. If the rooster used has dominant feather color coupled with recessive leg color you could get another generation of sexlinked offspring from your multigeneration sexlinked hens.
