I've noticed a bit of a difference between the buffs and the lights. The buff were great and the only breed I've had rooster of. Wonderful roosters. My light Brahma, though, was leagues above. She had the most gentle and amazing spirit from the get. Her calm, unbelievably chill nature affected the entire flock. She had some health issues and when she had to be separated, the whole flock changed. She got thru some crazy health stuff, to the point where she became known as Morgaine, the wonder chicken. She was the matriarch; when one of the girls had internal laying and got sepsis, after her surgery she slept under Morgaine's wing for at least a month and Morgaine was totally good with it. Even though, she was a 9.5lb bird, 3 lbs bigger than my next largest bird, she wasn't at the top of the pecking order. She was just not into that and did not participate in shenanigans, but she was somewhere toward the top of the middle. In fact, her affect on the flock, was so profound, it kept the shenanigans at such a minimum, it took me 3 years to notice their pecking order....and I spend a LOT of time with my birds. She was just a big fluff ball of love and everyone loved her. She also had a sense of humor and was just funny. Smart too, I taught her to count to 7, scratched my pant leg with her beak, to get a peanut. Best chicken ever....and I've had Faverolles, who were also spectacular birds.
