Then a fully feathered neck 'turken' or 'naked neck' is what it is, it isn't something else.
It may be a matter of semantics, since the breed name is also descriptive. That is, Naked Neck as a breed, versus a chicken with a naked neck, which is just a chicken with genotype NN - which could be a hybrid with another breed, or even a meat mutt backyard line brought to NN genotype over generations (something a lot of folks enjoy working on, especially in hot climates)...
I think as draye points out, it's just important that if there will be a transaction involved (e.g., selling naked neck chicks), there should be full disclosure.
