We have 15 hens total and one is a beautiful(if I do say) nankin bantam. She was one of the queens of our first group of hens and then we added a younger group. As the younger group has grown they have begun to pick on her... plucking feathers off her back. We have taken to seperating her from the group during the day when we are away. When we get home they free range together and then we let her go to the coop to roost. In the morning I find her and put her in a seperate area. Both my husband and I do not think that this is working as they are still picking on her and she has become more and more a loner. We wonder what we will do in the cold months to come. We need suggestions...hopefully economical ones. Thanks in advance for your input.
