Sex- linked Information

Any red rooster will do to make Red sex links. If that is what you are looking to do. there would be no guarantee as to their laying ability though. Anyway just any red rooster will do.

go back to post #669 and read till current..........

any monkey can throw two chickens together as long as one is red and one is white and make sexlinks. im wanting to take the cross to another level.

Not really. There are several white hens that cannot be used to make sex links. Not all white hens have silver. Some roosters pure for gold and showing some red will not allow the yellow or red to show up on the down. It’s not just having the hen with silver and the rooster pure for gold that works. The other genes have to go together in a way to allow you to see it in the down.

I’m not sure exactly what you hope to accomplish. Is it just a one-generation of good layers where you can sex them at hatch? Or are you looking for a sustainable strain of chickens that are great egg layers?

Once you use chickens to make sex links, they cannot be used to make more sex links. The first generation rooster’s genetics are split, no longer pure. The first generation pullets have exactly the wrong genetics to be used to make sex links. It’s possible that you could get some chickens in the second generation that could be used to make sex links, but that depends on what else is in the genetic stew. As an example, your RIW hens are going to add either dominant or recessive white to that genetic stew. Depending on how that pairs up further down the line, either of those could mask the silver or gold.

If your goal is the first, a one generational cross to make sex links, the red production red rooster over a productive hen with silver, which your RIW’s may possibly be, would probably be a good way to go.

If your goal is a sustainable flock of several generations, forget about making sex links. Get the best stock that fits your goals and select the breeding stock that carries those traits forward. You cannot sustain sex links through the generations but you can sustain egg laying traits if you select your breeding stock right.

Hear hear, I agree here too

or the other option is to simply buy hybrid sex links as they will out perform anything you can purchase and mix up yourself to make them, they aren't just a simple gold x Silver color cross, their genetics are generations old that have been bred into special varieties/not breeds just for these hybrid crosses.

You can cross a Pro-red over those white birds you have and produce a gold sex-links that will lay most likely as good as or maybe even a tad better(due to heterosis/hybrid vigor) than the parent stock.

yes. been there done all that.

im interested in the F1 generation. i know all about sexlinked fowl. had them for decades and have dabbled experimenting with them. i know not all "red" and "white" work. but was speaking in generalizations.
i was only interested in what others thought of a production red brood cock in comparison to the traditional RIR cock. OR if someone had other suggestions to use other than a RIR if the production red is not a true "red".........

i want to produce a sexlinked brood. raise them up for myself, and see how well they perform. and then if all goes well i will produce some for selling purposes. i have been generally impressed with hatchery quality sexlinked fowl till this last bunch. then after doing some homework, alot of hatcheries do what im planning. they dont have parent stock bought from hy-line or dekalb etc. so if they do it this way, why cant i?

but i need to get started and just wanted thoughts on the production red whether he was red or not, and if he would do better than most other types of reds.

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'

hopefully by this time next yr, i will be well on my way to knowing whether im successful or knowing wheather i need to scrap the whole idea, and keep buying ISA browns or hubbard golden comets cause these are best ive found yet.

i used to think this way too. but i was wrong. at least not for the few hatcheries i talked to. and after trying different hatcheries stock, im convinced that not all use genetically improved parent stock. some that advertise they use this type of stock truly do outperform most all the rest. the one that comes to mind is TOWNLINE.

I see where your going now
hey PM Freds Hens he's a mod on here. He has a thread dedicated to multiple generations of breeding sexlinks he can shed some light on your project I'm sure and can tell you the addy for his thread I would post it and still might if I find it soon enough. I'm slower than mole-asses on a cold morning.

You do know that there are a lot of hatcheries that don't even own breeder chickens and they buy their eggs from breeders (like Townline,Hyline ect) they simply just hatch eggs and quite frankly couldn't 'for real' tell you a thing about the birds they are selling.

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?
