Aleta,
Please let us know how the HRIR temperament differs. For those with small children, this is #1

I started that way, just because I could get them *now* and get laying hens locally *now*, whereas getting a Heritage line is a little harder where I live. Not for long, though! I'm gonna take over this town, I will! Bwahahaha! Ah hem. You will find that RIR (and I would think most any other hatchery 'layer') hatchery hens usually stop laying reliably after 2 max 4 years. IF they live a full 8 yrs, they will be the most un-useful birds around. This I CAN speak too...My RIR are very skittish but the males are 15 weeks and starting to put more meat on. I definitely will be sticking with my Black Jersey Giants they are fat and sassy and still have a good 6 months to maturity. My one Delaware roo is getting quite big too. I am willing to take my time and spend a bit more money for quality meat and happy birds.
I really didn't realize there was that much of a difference in temperament in hatchery birds. From my understanding heritage just means that they are naturally mated, slow growing, and long living. I can see where a breeder who specializes in a specific breed will focus on temperament more-so than a hatchery would.
Hatchery stock absolutely shows more temperament problems. When you flock breed 200 roosters in a pen with 2000 hens, who the heck is judging temperament? Or faults? Or lack of conformity to the SOP? Who is selecting? With a scene like that, which cock gets the most females? Why the hyper, dominate, aggressive one of course. Breed in this manner for a decade of two and guess which genes and temperament dominates that flock? No surprise. None at all.
When a Heritage, true to type, true to breed, true to standard breeder has kept a line going for 30 or 40 years, breeding maybe less than a hundred chicks per year, he/she knows every bird. Knows the temperament of the cock birds used intimately. Very often, has shown those birds to be judged, thus preventing barn blindness.
A difference? Oh my. Night and day. That's our experience.
