possible sex link?

Ok so I've been playing with this exact combination for a couple of years to see if I could get any consistency...Heres what I've gotten...I started with a completely closed flock of SQ white leghorns...I also had a Quad of SQ RIRs. I mixed the flocks and let the White roosters and RIR rooster interbreed. Last year I began to see speckled chicks...Mostly white but with black spots. I kept all the pullets and 1 of the roosters. This year I again have hatched some speckled chicks but now I am also seeing solid black chicks, again all hatched form white eggs, from either solid or speckled white leghorn chickens..I would suggest the the black chicks are the result of the RIR rooster over a speckled hen or possibly the speckled rooster over a white leghorn. As to the sex link factor that remains unanswered until I can sex the black chicks...In reference to the above quote, my RIR roosters over white leghorn chicks produce hens that lay white eggs, pure white...The search continues

You can use other white hens we only use RIW's here and have in the past used our Delaware hens you can also use a Wellie roo

you guys all rock my chicken world lol!

the eggs didn't come from my flock, i had isa browns, and a rir roo. the hens were old, and none of the eggs would develop, so a friend of my hubby gave me some of his eggs.....they were all white eggs, smallish compared to our huge isa brown eggs...one light brown egg with khaki spots ( hatched out a little red chick with gray wings, a gray head and a gray rump and spraddle legs poor little thing ) ANYHOW i know he has all white hens i do not know the breed/breeds if they are all the same or several different whites, anyhow, the only roo he has is a br, and the white eggs all yielded pale yellow chicks with black spots peppering their bodies AND an almost perfect carbon copy of a br....so that was why i was so curious if it was possible that they were sexlinked. i don't know the flock history so maybe the white hens and the roo could have other crosses too, i will post some pictures tonight, and read some posts here, been soooo busy tending to all the little chickies that i just haven't had much time to read like i like to do in the evenings lol. thanks for all the input, you byc'ers are so AWESOME!! have a wonderful sunday afternoon

is there more than one white hen?

The yellow chicks with black spots are usually the offspring of a dominent white parent (like white Leghorn). I hatched out a dozen of them myself but their daddy is a RIR. I was told that they should lay lots of light brown eggs so I assume that would also apply to a BR cross as well.

i think there are a bunch of white hens, and i don't know if they are all the same breed....only one roo tho

So true, I would say I know a good bit of genetics and most of everything I know, I have learned right here on good ole BYC.

Do you have any specific questions in mind ?

i have a million let me get back to ya later

So true.... I just list those two

White rock hen X RIR or NH = Golden Comets... cockeral hatch out yellow , also good size to butcher
White Leghorn hen X rir or nh = Red Star cockeral dont have much size to butcher


Using other white hens produce other named sex link

NOT Necessarily You have to take into consideration all the possible genetics of the white breeds.

You can't believe what a book says about the certain names of certain sexlink crosses, they all get mixed up, you can ask what breeds produce the golden comets and probably get about 10 different answers.

With the cross of the White Rock hens on RIR or NHR roosters, you have to remember that not all White Rocks carry the Silver genes and the silver genes in the hens are what makes the sexlinks, when they are with gold gene roosters of any breed, not just RIR or NHRs. And also, about them producing golden comets, golden comets are usually the red colored hens with white tails, the white tails comes from a hen with Dominant White AND Silver genes, White Rocks are Recessive White, not Dominant so if they did have silver genes, the would produce sexlinks with the hens haveing black tails instead of white.

It is very rare to get anykind of sexlinks using White leghorns, White leghorns usually never have the silver genes, leaving just a dominant white bird which will produce chicks that are white with black dots no matter what rooster she is bred to wheather he is gold or not.

Also with the black Sexlinks, as long as you have barred/cuckoo hens, you can breed them to any color roo as long as he is not barred or dominant white to get black Sexlinks.

i have a question about a possible sex link...here goes.

the hen is white, the roo is a BR.....i incubated the eggs myself, and i ended up with black br looking chicks, and pale yellow chicks with black spots all over their backs. is is possible that the blacks br looking chicks will be hens, and the yellow chicks roos? just curious i don't know much about genetics and such.

any input would be great, thanks
See they sticky note at the top of the Breeds, Genetics, & Showing list.
According to that you should have sex links. The blackish-brown colored ones should be pullets while the yellow ones should be cockerals. Then again depending on what breed the white hens were could make a difference. I've read that White Leghorns will not always be dominant white that they could be masking barred or black under the white. If sex link is what you're hoping for then I wish you all the best that these are what they are (Sex linked).

My bad.. Guess I got the breeds turned backwards in my head when I was replying. Sorry.​

I know some of the people who produce eggs for the hatchery.



They use white rock X rir to get golden comets
white leghorn X RIR to Get red star
barred rock X RIR to get black sex link.

These three I know...now other may use others and call them one of these names. The golden comet from this cross are buff with white under feather not dark feathers....Didn't read in a book, these are facts from flocks used to produce eggs for a hatchery. These are production bird not true show birds........

White Leghorn?
The White Leghorn doesn't carry the Silvering Gene need to produce a Sex-link....

White Leghorn are dominant white--
The dominate white (I) gene in manly found in the white leghorn. It is not completely dominant, being less efficient at suppressing gold/red pigment than black pigment.
In order to use White Leghorns in a Sex-link breeding it would have to be the sex-linked gene silver (S)..
