That makes more sense, since they're hatchery birds. The lighter body color actually looks better too me.The birds shown are poor examples of the coloring expected from New Hampshire Reds. The "darker neck" statement simply isn't correct. Good quality NHR should have an almost golden looking neck. In the SOP this trait is described as "brilliant chestnut red." I have attached an image of a very nice quality New Hampshire Hen from Whiskey Gulf New Hampshires and sourced their gallery. Hatcheries have been quite bad at preserving the differences between PRs, RIRs, and NHR. Essentially they're all derived from almost exclusively RIRs, just bred to different purposes/standards. Many hatcheries have reduced this to just color difference, the lightest colored birds being labeled NHR, medium PR, and darkest RIR. Obviously this isn't ideal nor am I saying that's the only difference, but personally, these birds are quite light in coloration so both PR or NHR are plausible breeds.

I'm picky when it comes to red Wheaten, a darker neck looks better on them.
Chesnut Red is a Dark Mahogany. The neck color of the SOP is misleading. It's more in of a Red Golden.
Dark Mahogany neck.
