Probably Production Reds. Most hatcheries (where feed stores source their chicks) don't really have Rhode Island Reds, but Production Reds, instead. They just label the birds that are a bit darker (not the proper deep, mahogany), Rhode Island Reds; mid-toned birds get labeled Production Reds; and the lighter red birds get labeled New Hampshires. Basically all the same thing, but slightly different shades of red. For true Rhode Island Reds, you need to go to a breeder.
