Wow, this thread is all over the map! What one person loves, the next person detests! I've seen several say they couldn't stand RIRs. Mine are curious, mostly friendly, and a couple of them like to sit in my lap while I'm watching Chicken TV. Mine are at least friendly enough to eat out of my hand, tolerate some petting, and let me cuddle them when they're getting ready to roost. My RIR roo Sarge went through a bit of a mean spell when I introduced the youngsters (7 Australorps, 6 RIRs, 6 BOs, and 2 BRs) to the adults, but once he had them convinced that he and he alone was top roo, everything settled down very well. The Australorps are a bit too pushy with the others, thinking that they (the aussies) should be FIRST to eat and LAST to leave the food, only when their crops stuck out like grapefruits... The buffies are sweeties and will be lap chickens occasionally. My BRs (one hen, one roo) are both sweeties, but hands down, the MOST friendly and cuddle-babies are the younger Golden Comets (and that could be more age-related than breed). Of the BB Red trio, the roo doesn't much like to be picked up (but then again, what roo really does?), but will tolerate some cuddling. Once I actually have them in hand, the two girls are very sweet and will just settle down & go to sleep.
ETA: my RIR roo and SLW hen are from a private farm, my RIR hens are hatchery (but from what I hear, VERY nice! DARK mahogany, shiny feathers), BOs are hatchery, BRs hatchery, AusLorps hatchery, GCs and BBReds from farmers/breeders I met at the Mayfield KY Trade Day).
