I want to introduce barred and laced (preferably double laced) patterns to my Naked neck group. I have no idea the genetics behind their colors as the 4 are hatchery stock. I had planned to get a cuckoo marans and a barnevelder (maybe a laced Wyandotte too) to the flock and only keep any chicks that had the naked necks to see what I got. Is this logical or is there something else in forgetting?
For white bars on black chickens, it's fairly easy because Extended Black is dominant, and Barring is also dominant. Because Barring is on the Z (sex) chromosome, you will get different results from a barred father vs. a barred mother.
If you get a barred hen (Cuckoo Marans, Barred Rock, Dominique, etc) and cross to your naked neck rooster, you'll get sexlinked chicks: males black with white barring, females black with no barring. Both genders are likely to have some other color leaking through in places-- look for photos of Black Sexlinks, because they will look a lot like that except that they will have naked necks too.
If you get a barred rooster and cross him to your naked neck hens, both genders of chicks should have white bars on black (again, with some other color perhaps leaking through.)
Laced and Double Laced are a bit more complicated, but because the naked neck is caused by a single gene, there's a fairly simple method to can get the naked neck trait in a bird of any color.
Get a chicken of the color you want, and cross to a naked neck.
Pick a chick who has a naked neck and cross again to the color you want. If you hatch enough chicks at this stage, some should be the right color.
Or you can pick ones that are close to right, and again cross them back to the color you want. (Continue crossing to the desired color for as many generations as you like, making sure to always have at least one naked neck in each pairing.)
By the time you've got the color right, you're likely to have a bunch of other traits from that breed too, so they may not be much like the original naked necks-- more like "Barnevelder with a bare neck" or "Laced Wyandotte with a bare neck."
