We have 9 hens and one is obviously the boss hen. The other 8 we thought were molting as they have lost feathers. They have never stopped laying everyday and then we became alarmed because the 8 hens have bleeding spots . We have watched for a while and found that the boss hen is pecking the others and eating the feathers! The boss hen still has all her feathers and looks very healthy. What could be wrong? They are on layer feed and they get a few table scraps once a day.
