I have 3 hens that are 7 months old. I got 3 more hens that are almost equal in size about a week ago. My three original hens are pecking at the other hens and not letting them eat or drink. The new hens just retreat and sit on a perch inside the coop most of the day. Today, I had a friend of mine tell me to rub Vick's Vapor Rub on their beaks (while they are in the coop during the night) allowing the rub to overpower their sense of smell. She said that it works for her when she introduces new chickens. Has anyone else tried this and what was your outcome? Please respond only if you or someone you know has done this. Thanks.
