Yes, at least half of a naked neck chicken's offspring will be naked-necked regardless of what they are crossed to. The gene is incompletely dominant, meaning that one copy of the gene gives a partial effect, as stated in the previous post causing the neck to be mostly naked except for a tuft on the front, and two copies of the gene gives a full effect, generally a completely naked neck. Since it is dominant over being fully feathered, any chicks that inherit it will express it in some way.
So, if the naked neck parent has two copies of the gene (and thus has a completely or almost completely naked neck), then all of his offspring when crossed to a fully-feathered hen will inherit one copy of the gene and have naked necks with the tuft on the front.
If the naked neck parent has one copy of the gene (and thus has a mostly naked neck with a tuft on the front), then only about half of his offspring when crossed to a fully-feathered hen will inherit the gene and have a mostly naked neck with the tuft on the front. The other half of his offspring will be fully feathered.
