My new Welsummers are the mean girls of my chicken run. I swear, I had to build a new roost just so they wouldn't kick the two smaller chickens off one at a time. They're the newcomers too! And just beyotches. They gang up on the others... I actually was happy when I saw a couple of our old hens (Buffy and her sidekick Willow) corner one of them alone and take her down a few pegs... After that, they were much better behaved!
