The term "heritage" is a recent invention and is basically a way to market purebred, Standard bred birds to those who may wish a well bred bird, but do not have an interest in exhibitions, per se.
In poultry, when a bird meets the Standard written for the breed, it is said to be purebred.
Your male that you found is fairly "pure", but he has some issues. His tail is pinched and is far too high, according to the Standard for the Rhode Island Red. He also looks to have a bent toe or two and his comb has too many points.
This particular thread is not dedicated to posting pictures of generic or hatchery or barnyard bred birds, but is specifically dedicated to discussing the breeding, showing and keeping of high quality, true-bred, bred to Standard Rhode Island Reds.
All that said, I'm glad you are taking care of that cockbird, Johnn. He's in good hands now.
