Naked neck genetics question

[Amanda052389]

I have two naked neck/cochin hens- one is buff and one is black. I would like to breed them and have more naked necks. I do not have a naked neck rooster-only Welsummers and a barnyard mix rooster.

I recently hatched out 14 eggs from all different breeds and only got 1 naked neck. I wasn’t sure how many NN eggs made it into the incubator because the eggs are similar in color to some other hens.

Anyone know my odds of hatching out more naked necks?

I’ve attached a picture of one of the hens and the only NN chick that hatched.

The NN gene is a dominant gene so whether a chick gets one or two genes it will be a naked neck.
Usually a chicken with one gene has the patch of feathers in front at the bottom of the neck as your pictured hen does. If they have two genes the neck is bare all the down to their crop.
A hen with 2 genes would produce all chicks having 1 gene and being NN when bred to a non NN rooster. Your hen bred to a non NN rooster would average 50% NN and 50% non NN chicks.

So if I’m understanding this correctly- I have a NN hen with 1 gene and being that I’m breeding her to a non NN rooster I have a 50% chance of having NN chicks.

Correct
