He's a Production Red, however he's dark enough that he might have been marketed by a hatchery as a Rhode Island Red. Technically speaking, there is little or no difference between hatchery quality RIRs, NHs, and PRs. If they are of a darker shade of red (closer to mahogany) the hatcheries often market them as RIRs. If they are of a lighter shade of red (closer to chestnut), they often market them as NHs, or sometimes incorrectly as New Hampshire Reds. And if they are somewhere between or very uneven in color, they are marketed as Production Reds.
