I've not seen anyone say on here that those stores or hatcheries accuse them of selling a bird that is SOP. Many people I know of will say I have a such and such type of dog or cat and they are likely not pure bred pets either. If someone looks around and reads much here on BYC they soon realize that you need to go to a reputable breeder to get a SOP bird.Hatcheries and farm stores, don't sell RIRs, even if it has a black tail, it's not a RIR. True RIRs are only available from breeders who have made sure to keep the breed pure, and they didn't obtain theirs from hatchery stock.
