Gorgeous!
I'm still pretty new at chicken-ing, lol, this being our 3rd year in. Most of our more standard breeds are from feed stores. We've had a few mean males, but I think part of that was our fault. Our females are sweet, friendly, and though not all lap chickens, they will certainly follow you around. However, I definitely see the difference in your bird as opposed to the barred rocks I've got. Even the ones I got from a local young(teenager) breeder, were not like this!
Some people will just take hatchery birds and breed them. It would take many generations to get a good, show quality, bird starting from poor stock if you even get there ever.
