My Rock, Silver Lace and Ostralorp hens began to lose feathers in February. At first I thought it might might be due to moulting, however this has gone on for several months. Their backsides and breasts are very red and dry looking. Occasionally I see one of both of the Rhoadies pecking them and wonder if the skin issues are from that or could they have a skin disease. They were hand raised, have had good nutrition and egg production seems ok. They are 14 months old and otherwise vigorous and friendly. Any preparations out there that would discourage the pecking but not burn their tender skin? They look moth-eaten and pathetic.
