Why yes there is a book but it is hard to find. It was written by Mr. Bernard Kellogg, the founder of the National Naked Neck Breeders Society.
To get rid of the bow tie pick the birds with the smallest bow ties and breed them and just keep selecting for the smallest. Sometimes it works and sometimes it doesn't.
There are two types of NNs. Homozygous and Hetrozygous, most of the time the homozygous will have the smooth necks as they have two dominant NN genes whereas the hetrozygous will often have the bow tie as they just have one dominant NN gene. The reason for breeding the two together is to get a high percentage of the smooth necked birds. I prefer the smooth necks, Teva on the other hand likes the bow ties.
It is my understanding that every chicken has the genes for the NN it's just that in most it is a dormant gene so don't let your Cochins get too close to your NNs. LOL
Les it's good to have you back & wish I had seen this post sooner. I am just finding it.
I have been told by one breeder that breeding homozygous to homozygous that you will usually loose your vigor & head shape ect. How do you breed & do you notice any lose of vigor ect.
Those Cochins are DD & I won't get to play with them, I am going to use a RIR with a hetrozygous as you suggested to get the leg color right & go from there.
