Are you finding feathers in the coop or run? If they do a soft molt, it's very gradual and you may not notice it on the bird itself, just from the feathers. Though if it's really slow and gradual, and only a couple feathers here and there over a long period of time, even that may not be very noticeable. My DSL Barnevelders did an extremely gradual soft molt that started in July. I'd find a feather or two here and there, and no eggs from them. It took them 3 months (!!!) but they are pretty much done with the molt now. They never had bare patches or looked raggedy. Very stealthy! My Orps, on the other hand, drop whole bunches and have naked patches, but are done with the whole thing faster.
Do you have light in the coop by any chance? If you provide supplemental light, their bodies may not be getting the signal that it's time to molt, since that's tied to the length of the day.
Other naked body parts like combs and feet have evolved to withstand winter without feathers and have mechanisms for doing that. The neck, on the other hand, has not evolved to be naked in cold winters, so it can't be good for them... Maybe they stay hunched and huddled a lot, so the feathers from the rest of their body cover the neck some?

I always wondered what they do in cold climates. Do people knit scarves for them?NN are great for hot climates,, as they tolerate HEAT better than other breeds.
