My buff is so, so stupid that even my neighbor who has never been around chickens has commented on how she thinks she seems "different" somehow just from watching her activity compared to the rest of my flock. I do have a barnevelder who is being mercilessly picked on and the buff is the only one who doesn't mess with her. She sticks close to the barnevelder and grooms her and will let her sleep next to her at night on the roost bar, and that makes me love her for being so sweet. I found an old pic of my Lenny to post and she's even with the barnevelder in that pic
