Sex- linked Information

[SJ]

If you want a dominant white male bird that is gold, you will have to produce one; red sex-linked males carry both silver and gold.

You dont HAVE TO produce one seeing as a white laced red cornish roo is gold and dominant white. You will get sex-linked but probably lose some laying ablity from a RIW. I used a WLR cornish over Delawares and SLW for sex-links. All the females hatch gold/yellow or orange (Im color blind, ok!!

) and the males hatch white. Some males have black specks. I think the specks have something to do with the Delawares barring but IDK. The males make for fine meat birds on free range and the females look pretty much like their daddy and lay a respectable 150+ medium sized tinted eggs a year.

A production red would be a good choice over rhode island white. Production red have been bred to produce lots of brown eggs and should be a better egg layer than a rhode island red. Jeff mentioned heterosis and this is the key to producing outstanding egg layers. The production red and rhode island white have to "nick" and get the proper gene combination to produce a superior egg layer. In order to know if you have a superior egg layer, you would have to run egg production trials throughout the life of the offspring and statistically analyze the data. With out the data, you will never know if they are actually superior layers. You will have to work with and maintain the production red line and rhode island white line to insure they maintain the ability to nick and produce the heterosis. It requires lots of time and expertise.

"so from what ive gathered, some say yes, it will work or i can use a typical sexlinked rooster that is also white (looking) but is red on the inside. cross this over my riw hens and voila' end quote

I am having a problem with this statement. What are you wanting to produce by this cross?

If you cross a red sex-linked (RSL) male over a RIW hen- half of the females will be silver, the other half will be gold and can not be used in a sex-linked cross. None of the male offspring can be used in a sex linked cross; none of the male offspring will be pure for the gold gene. The only offspring that can be used in a sex-linked cross are the silver females ( these females are from the RSL x RIW cross).

If you want a dominant white male bird that is gold, you will have to produce one; red sex-linked males carry both silver and gold. The male you would use in your proposed red sex linked cross would not be white but red/buff with white in the wings and tail. Regular red sex linked males will be white looking but carry both silver and gold. In the red-sex linked male, the silver is incompletely dominant ( straw hackles) and autosomal red will also show on the red sex-liked males shoulders and back ( similar to red pyle).

You can not produce a white looking bird that is hypostatic gold ( white looking but red on the inside) using dominant white. You would have to use recessive white to produce such a bird. Recessive white is not used in sex linked crosses because it would effect the down color of the sex linked chicks making it very difficult to tell the difference between the males and females.

Are you wanting to use sex linked offspring to produce ( after a few crosses) superior purebred gold males- and then use the purebred gold males and silver females you produced in a red sex-linked cross?

Just have to say thanks Tim. This thread has been a wonderful source of useful information.

Would the result of crossing a Dark Cornish cock over a Light Brahma hen give a sexlinked chick? Is the Light Brahma a silver? Thanks in advance. jeff

If you look in the very first post in this thread, you'll see a chart Tim put together that shows what you can mix to make sex links. Look in the Red Sex Link table in that post. You'll get your answer.

Have a couple questions --

FIrst let me preface the information with--- I hatched a number of blue cuckoo maran eggs and the head spot was very visible: white on gray.

KNowing this I put a number of black barred hens of various lineages ( tracing back to a black barred rooster) with a black Americana and a blue ameraucana. Both have red in their hackles.

Will I have trouble sexing the chicks when the hens carry a hidden red?

If both males are double black, I should not have any red chicks, correct? THese males are supposed to be pure bred . . . .


I was planning to add silver laced wyandottes to the mix. THese chicks will not have a spot on the head, one will be silver based and the other not. I think I will need to hatch these eggs separate from the above eggs, correct?

Red not a problem.

The chances are very small that you would hatch a red chick.

You will be able to tell the difference between the sex linked chicks and the wyandotte chicks.

I was referring to offspring from a red sex linked cross. In order to obtain a egg production type male bird ( purebred for gold and dominant white) that can be used in a sex-linked cross, you will have to make one by crossing a red-sex linked male and female. Then select from the offspring the appropriate males. I know of no male American breed that will fit the bill. The bird would be a white tailed red. There are white tailed red female hybrids; red sex-links.

The chick closest to the bucket was sold to me as a female sex-link... but it's not red, or black, and it's barred. What's the deal?

That's them at a day or two old. They were a chocolate brown, no red or black.

Looks partridge, they look barred as chicks, the lacing comes it around 4 months, when thier adult feathers come in
