Ha-ha..I had to separate my Reds into another coop last fall from my Buff, Astrolorp, and Barred Rock because they were picking on my Buff terribly. I let them see each other through the chicken wire yesterday and the Reds started going after my Astrolorp this time! And she, like the Buff, is a gentle giant. They were pecking her face right through the wire. Am I just screwed thinking they will ever all get along??
