Thanks so much BCBoy.
Enjoy those shanties. I enjoy them myself with one of my friends who is from NZ. Smile and please share more pics. I like seeing them as we'll!

the shandies really helped. My world has been shaken, having had nits myself it freaky unpleasant, I am impressed they are even laying eggs (haven't had any more green ones though). I believe we have lice out there, no sign of mites and this is good news to me.

I will share more pics again. it is good I think :-).

Coopslave, you said that the barred boys give barring to everyone, that it is the barred girls who will give sexlink chicks. did I understand that correctly? if so, if I crossed a barred rock hen with a wyandotte rooster would I get sexlink chickens? yep, I'm in preschool genetics. I get overwhelmed with too much information - I'm a baby steps learner :-)

A red, gold rooster over a barred hen will give you sexlink chicks.
Same as red, gold over silver will give you sexlink as well.

Missed the shandy comment. Love them, especially on a REALLY hot day!

Black Sex-linked

There are two important genes that must be a part of a black sex-linked cross; the E locus allele called extended black (E) and the sex-linked barring gene (B). The Barred Plymouth rock carries both E and B and both genes are used as the female side in commercial black sex linked crosses while the male side of the cross is a Rhode Island Red or a New Hampshire. Birchen birds at times can be used in black sex linked crosses. It is best to leave the use of birchen birds to individuals that have tested the birds for the correct genotype. If birchen birds do not have the correct genotype, the offspring will not be black sex linked.

A few specifics to remember about a black sex-linked cross are:

1) the female must carry sex-linked barring (barred),

2) the male can not carry sex-linked barring (male can not be barred),

3) one of the birds must be homozygous for extended black or carry two extended black genes and

4) neither of the birds can carry dominant white or in other words be a white bird. Some recessive white birds may work on the male side of the cross but you never know if it will work or not work. So I suggest not using white birds.

5). Almost any variety (color) of male ( not including white or barred ) can be used in a black sex linked cross. White birds sometimes carry dominant white and or barring which would not work in a black sex linked cross. White males that do not carry dominant white or barring will work as the male in a black sex linked cross. White males like the white wyandotte or the white plymouth rock will work if they do not carry dominant white or barring.

In a black sex-linked cross, the female will only contribute the barring gene to the male offspring. So the adult males will be black and barred. The female offspring will receive their sex linked trait from the father; in this case, the recessive gene for no barring. So the females will not be barred as adults.

It  is also important that the chick down has a black dorsal surface, back and top of the head; this allows for the barring gene to be expressed as a white or cream spot on top of the male chicks head. See Illustration 5. This is why a white bird that carries dominant white can not be used to produce black sex linked chicks. The top of the head would be white and the white spot will not show.  Males that carry barring can not be used because the males will produce females chicks with white spots on their heads.

The top of a  female chicks head will be a solid black color.  See Illustration 6. The chicks in the pictures do not have a white belly like many other black sex linked chicks.

1 Male carries the blue egg shell gene.
2 Not a good choice may carry barring.
3. Carry the genes for white egg shell.

I'm having tight chest anxiety with this, I am forcing myself to learn genetics!  I refuse to be overwhelmed, nearly clicked on the x BCBoy.  That is slightly more than preschool genetics for me but I am "going in"  pale .  It is an excellent and easy to read piece of information and I will study it more. just have to go over it many times to learn bigger chunks of information.  I think I have a birchen chicken  =  she is black australorp x amerucauna and has the pretty feathering on her chest.  Will add a picture later and also take more time to read the material you put on here for me to understand.  Thank you.

Coopslave  .  . . if I crossed the BLRW (not white) rooster over a barred rock hen, I'd have sex link chicks?   Ya, nothing like a shandy on a hot hot day.  just the shizzle.

this is Raven, she is now twice the size and looks more like a Black Aiustralorp pullet, in fact I have to look for her pretty chest feathers at a quick glance to be sure I'm looking at her.  She didn't think much of an evening photo shoot so had to find an older picture but it shows the pattern really well.  Is this the birchen effect?

I believe so, you would get black or blue chicks with the white dot on the top of the male heads. I used Barnevelder over Barred Rocks and Light Sussex and found it worked very well.

Dark Cornish over Light Sussex will give the red sex link chicks correct? Gold roo over silver hen? White males gold females? How is the Colombian pattern from the light Sussex transferred over to the chicks?
Magdelan the color on the front of that pullet reminds me of the coloration on the silver Sussex.
And I'm hijacking your post. Sorry.

those silver sussex are quite striking to look at aren't they, my light sussex hens have big single combs and lay big eggs. They are nice chickens ;-).

I looked up red sexlink chickens are and wikipedia says:

Red sex-links are a cross between a Rhode Island Red or New Hampshire rooster and a White Rock (This variety pair is known as a Golden Comet), Silver Laced Wyandotte, Rhode Island White or Delaware hen. One example of a red linked breed is the Red Shaver. Europe has the Cream Legbar (an actual true-breeding pure breed) and ISA Brown sex-links, which also are found in Canada.

This is what I`m going to use.

Oh that buckeye guy is handsome. I liked KathyS' buckeye's and she has the RIR with rose comb. will this combo you have planned make a sex link chicken? do the genetics work out for it? I still need to go back and read the info you put up. need to stop having conversations and do the work!
