We just got a new Buff orpington hen, 1 year old, named Nellie, and at her last home she was bullied. Now, she is being bullied by my barred rock, Gloria... and Nellie is bullying my other (partially blind) buff orpington, Penny. Gloria is trying to protect penny by chasing Nellie away whenever she comes near to eat or drink. Nellie is also afraid of me and my dog. (In her last home, a hen got taken by a dog/coyote.) Is it time she needs? And do some chickens NEVER get along?
