Do they? I have a SLW Rooster, 8 months old, sexually mature, who has lost his back feathers over the cold months. His back is not bald, there is signs of fuzzy new growth. This is only on his back. His cape is gorgeous and beautiful tail (sickle) feathers, wings, etc. This feather loss is directly on the top of his back. Sorry, no pictures. (Technologically handicapped.) Everyone else is fine, except his hens who have bald backs. But that's due to his over active sex life. Now I have chicken saddles!
