My BR roo is sweet and smart (see the favorite rooster thread for the full story.) He's the favorite rooster that I've had.
I have several White Rock hens that are my favorites among the females. They are the first to investigate things for food--they peck what they think is food, but that's not aggression. One of them, "Molly," follows me around the yard when I do my gardening, scratching and pecking in the dirt where I dig, sticking her nose into *everything* that I do. She can be a nuisance when I'm trying to dig out a tree root or something, but it's nice to have someone so interested in what I'm doing!
They are the SMARTEST chickens in the bunch. I love 'em. All mine came from McMurray.
