We had 4 hens in varying degrees of feather loss due to others picking at them. I separated them fro the main flock and made chicken saddles for them. They look really cute in them and it generally stopped the picking on their backs. They are picking the feathers on the back of their heads .... So now I will get out the Vicks. But the saddles to protect their backs are great. If you don't sew, find someone who does to help you out. They are expensive to purchase, if you need several, and easy to make. They also protect their backs from the Roos when breeding.
