I have a hen that is part of my original group. She has been picked at by the rest of the hen the past week and now almost has no feathers left. Her neck and head are bare and now her underside and tail feather are going too. I can't figure out if it is one hen or all of them abusing her. They have been cooped up in the coop and run due to weather and some neighbourhood dogs that killed half my flock. I am putting vinegar in the water, have a cabbage hanging on a string in the run and give them scratch but it is getting worse, not better. I am thinking I should remove her so she can heal but won't that make her position in the pecking order worse? She hasn't laid in two weeks either.
