I can understand what One Chick Two is saying. I have Production Reds and Heritage RIRs. In my research the original RIRs were created to be dual purpose, not show birds as they are today. Probably the feathers of the HRIRs today are darker than the original. My heritage RIRs are not dual purpose, but they were advertised as exhibition quality. They are heavy, compact, and brick shaped, with very dark feathers which are a little stringy. Poor egg layers, and the shells are not as thick as my other breeds' egg shells. They may be poor layers because they lay for a short time in the spring, and then they all go broody. Two go broody twice in a season. They also are very sweet and shy. Just pointing out I think she is right about the original purpose of the Heritage RIRs and they probably are different today than they were then. Maybe this is already covered in this thread and I'm repeating, but I would go cross-eyed reading all the posts!
