Our 4 hens have all been raised together. An Orpington, Cochin, Bard Rock and an Amercuana (we think she's a bit of a runt, she's smaller amd not yet laying). The Cochin started pecking at her A little at first. I noticed she has started packing at the other two chickens. And tonight, she would try to push the Americauna off the perch. I moved 2 chickens down and put the Americauna between the nice girls. The Cochin still tried to peck her and the Orpington. Is there a way to get this to stop? I don't want to have to get rid of her, I can't live in the chicken house and I don't want my other girls getting beat up! It's high school pecking order in there!
