I bought some Silver Laced Wyandottes at a Rural King in KY. They're only 2 weeks old and mean as heck -been feather picking. I bought some special meds to put on my poor Brahma, and after they realized she tasted yucky, they moved on to two other victims. I had to sit and watch to see who was doing it, and realized they're just a gang of bullies. One was literally standing on top of another chick, while the others pecked it's tail feathers. I removed them to a separate brooder (my whirlpool), and now everything's fine. I have some more of the same exact breed I bought at a local co-op, and they're nice. I've never seen mean little chicks before.
