Heritage qualifications:
Heritage Chicken must adhere to all the following:
1. APA Standard Breed. Heritage Chicken must be from parent and grandparent stock of breeds recognized by the American Poultry Association (APA) prior to the mid-20th century; whose genetic line can be traced back multiple generations; and with traits that meet the APA Standard of Perfection guidelines for the breed. Heritage Chicken must be produced and sired by an APA Standard breed. Heritage eggs must be laid by an APA Standard breed.
2. Naturally mating. Heritage Chicken must be reproduced and genetically maintained through natural mating. Chickens marketed as Heritage must be the result of naturally mating pairs of both grandparent and parent stock.
3. Long, productive outdoor lifespan. Heritage Chicken must have the genetic ability to live a long, vigorous life and thrive in the rigors of pasture-based, outdoor production systems. Breeding hens should be productive for 5-7 years and roosters for 3-5 years.
4. Slow growth rate. Heritage Chicken must have a moderate to slow rate of growth, reaching appropriate market weight for the breed in no less than 16 weeks. This gives the chicken time to develop strong skeletal structure and healthy organs prior to building muscle mass.
Chickens marketed as Heritage must include the variety and breed name on the label.
Terms like heirloom, antique, old-fashioned, and old timey imply Heritage and are understood to be synonymous with the definition provided here.
Abbreviated Definition: A Heritage Egg can only be produced by an American Poultry Association Standard breed. A Heritage Chicken is hatched from a heritage egg sired by an American Poultry Association Standard breed established prior to the mid-20th century, is slow growing, naturally mated with a long productive outdoor life.
Production bred birds are bred solely for egg production and often for profit. In most cases they're from hatcheries, who keep them indoors in large, crowded areas and most live a short life. They are not slow growing, often have their traits such as broodiness or gamefowl behavior bred out, and are not bred to the standard (And, who and what mentioned perfect show quality? The standard is simply the breed standard. Breed away from it and you don't have the breed anymore. . It's just a bird that is labelled as such but doesn't adhere to any of the labelled breed's standards.

For example -
A Production Red is simply that. Often it originates from the Rhode Island Red and still can be, however in general it is a yellow shanked, red (or reddish orange) colored, brown egg laying, single combed bird that lays a LOT of eggs.
A Rhode Island Red is a yellow shanked, dual purpose, slow growing, large breed with dark red plumage, a single comb, a level set tail, and good amount of brown eggs. It also should at LEAST weigh 7 lbs for a cock, 6 lbs for a hen. It should also have a long span of life and production, regardless of how good its production is. It should be self-reliant, allowing both meat and eggs for a long time.
