A naked neck chicken will always produce at least half naked necked chicks, no matter what they were bred with. It's because the NN gene is semi dominant. Semi dominant means there's a visible difference between an animal with one or two copies of the gene, a great example being the color blue in poultry. Birds with one copy look and are called blue, birds with two copies are called splash and look plainly different. (not literally so black and white like that.. the occasional blue can look splash-ish and some splash could look like pale blues...)
The difference with naked necks is the bow tie size.. birds with one copy usually have a big bowtie with lots of feathers covering all or most of the front neck. Can't see the crop too easy. Birds with two copies look 'very naked' compared to these.. the bowtie is either completely lacking or is very small with few feathers on each side.. neck and crop are right there for everybody to see. Comparable degree of nakedness can be found on the body by lifting the feathers..
Birds with one copy of NN bred with anything not naked neck- a rock, brahma etc will give half naked neck and half not chicks... birds with two copies will give 100% naked neck chicks with anything.
Both parents with only one copy will give 1/4 not NN, 1/2 with one copy and 1/4 with two copies NN.
Have fun with your projects and be sure to post pics, including on the main NN/Turken thread! :)
yeah I did get some chicks from my NN rooster that didn't have naked necks ... The ones I did they all had bowties like their dad though :) .... I didn't get too many chicks though which stinks. I do have a daughter from my NN rooster.. She is half Australorp and I have her with my Light Brahma rooster and I have set some of those eggs. I hope some will be Naked Necks like her I can only hope :) :).... It was weird to see chicks that weren't Naked Neck like their dad and to see their siblings have the Naked Neck...
