I have had four hens for several months now. Two are six months and two are five months. We have kept them in an enclosed run with a roosting box attached. Yesterday shortly before sunset we decided to let them free range in our backyard for the first time. Well the silly girls could not figure out how to get back into the roost, so I had to catch them and place them back in. The very next day they started picking on one of the younger hens. I believe this was the hen that made quite a racket when I caught her to put her back. They peck at her until she runs back into the roost. If she comes out they attack her again. I put some food and water in the roost for her, not sure if she is taking any. None of my hens have started laying yet. I don't know what to do for her. Our space is limited. Do these things tend to pass? Is there anything I can do? Thanks for your help.
