How do I breed or obtain a Barred Rock/Silkie mix?

[Chickooster]

Hello. I was wondering if I can develop or obtain a Barred Silkie mix. After viewing a few pictures I started to grow fond of them. I currently have a female Barred Rock/Cochin and several Silkies of different colors. Thank You

Hi, welcome to the wide world of genetic learning adventures!

Seriously... it's called cuckoo Silkie... and I am currently trying to achieve the same thing.. or at least considering it. Though I already have paint and my real goal is Lavender Silkies!

You can breed the barring into any color you like. The feathered legs and beard should be dominant but you will have to breed back another generation to get back the Silkie feathers. Also there is the five toe and bantam thing, plus skin color and comb type...

A barred female crossed to a solid color... red, black, blue, even black copper, just NOT striped, splash, partridge, laced or white.. male will produce sex linked offspring. Where all male chicks will have a white spot on their head and will be barred when they grow out. The females will all be a solid color.

My goal is an actual cuckoo Silkie in the end not some rock Silkie hybrid thing.

This is at least my current understanding. If you do come across Cuckoo or Lavender Silkies anywhere, please try and remember me.
Being interested in breeding what I want in a bird has really advance my enjoyment of chicken keeping and made it soooo much m ore interesting. Man if they could have piqued my interest like this back in school!

In the meantime, this genetics calculator may help anyone who wants to breed for a color. This genetics calculator is run by the same site and is specifically for crossbreeds. It's a bit complex for my taste (I'm really only interested in colour) but it might interest you.

Actually splash, partridge and laced males can be used for black sex link crosses. Barred, cuckoo, dominant white and possibly some birchen birds cannot.

The first post in this thread discusses the various sex links

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 chick’s 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 chick’s 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.
