A production Red or RIR is a hatchery bird not a hybrid. These birds are not selectively bred to the standard for its looks. It doesn't mean that they are not going to be a good bird, but chances are they won't be as good as a breeders would be!
Most hatchery Rhode Island Red's are sold as a laying hen now. Unfortunately they have some what lost their rich colour and size. On the other side of the coin, some breeders now try to achieve that text book looking bird, but the egg production has suffered.
I'm not sure what a certified breeder is, but there are still lots of people out there that have very nice, original Rhode Island Red flocks. You'd just have to look for them.
FYI, If you cross a RIR rooster with a Barred Rock hen, you will get a hybrid bird called a Red Rock cross. Some hatcheries have different names for them as well. The crosses you'd get from the hatcheries are very good layers! Also, the chicks are sex linked. The hen will be black with a sunburst on her chest and the roo will look like a Barred Rock.
