It can get confusing as pure NN can mean two things: 1. The breed. 2. Birds pure for the naked neck GENE.
For #1 the bird will have to match the Breed Standard in every way.. in the accepted color, with the right body type, right color legs etc.
For #2 it is possible to tell if a bird is pure or not pure for the naked neck gene by looking at it. The naked neck gene has what's called a "dose effect".. which means there is a visible difference between a bird with just one or two copies(pure) of the gene. One example is Blue and Splash. Blues are birds with just one Blue gene and Splash have two copies of the Blue gene. And you can tell if a bird is a blue or splash by looking at them. Similar effect happens with NN.. not pure NN have a much larger bowtie that covers most of the lower front of neck and hides the crop.. birds pure for NN have a much smaller, very tiny and a few even have no bowtie at all. Their lower front necks, crop area and shoulders are very naked and visible. You can even see the difference on day old chicks:
Pure.. looks totally bare necked but you can see two very tiny puffs high up on neck:
Also pure, and happens to be completely naked necked- those are not very common:
On left is not pure, on right is pure:
(Oh yeah, I have 24 NN egss under my BR, 4 have hatched. GLW Naked Necks and Red Star Naked Necks are what she is kindly hatching out for me. Also how do you make NN so they lay colored eggs? Breed with a EE? (Maybe get a breard too!!) thanks
It's very easy. The naked neck, beard and colored genes are all dominant so all you need to do is cross a naked necked rooster with hens that lay blue or green eggs.. if they have beards too, you will get naked necked chicks with beards, at least half will lay colored eggs too.. I want to see your GLW NN! I am working on laced NN myself.
