We have 3 Americauna hens in our little city flock. This spring, we got a fourth chicken, a rhode island red that we named Polly, since our city allows up to 4 hens. We have been raising her apart from the flock because we didn't want her to get picked on since she was just a little chick. We put her in the coop during the day, while the big hens are in our chicken tractor. At night, we move the big hens back to the coop, and put Polly in the tractor. We'd like to have all of them living together by winter, since we'll be unable to use the tractor because we get lots of snow. But every time we put Polly in with the big girls, they chase her around and peck at her. What is the best way to integrate her into the new flock without her getting pecked and bullied? Or will she get pecked and bullied no matter what we do?
