I read that Buff Orpingtons often get pecked because they are so docile. This is the chick that the StepMama hen nearly pecked to death when he first hatched because he wouldn't stay underneath her. He is very active and loves to trill and fly. So I've suspected Buff Orpington as part of his make-up for some time. My mom had BOs when I was a child, and many of his golden feathers seem about the right color for a BO in my opinion.
There are no feathers sticking out the sides of his cheeks but he does still have the bad peck marks at his temples. I used Rooster Booster on them, but they haven't healed yet. He grooms himself a lot-- lots of dander and fluff coming out everywhere.
The egg owner doesn't seem to know much about breeds. Maybe he has Ameraucana chickens, and he called them Aracauna? But with no cheek tufts, perhaps this little cheek is part BO and half Leghorn. That could explain his super-sweet disposition?
