Can someone help me? I recently posted a message about my chicken missing feathers on top of her wings. I thought it might be molting, but upon further inspection it's looks dry and irritated. It looks like the skin could actually be dead because it's not at all the same color as the surounding skin. Plus, the tips of her feathers are actually just quills, no feathers at all. We have had some colder than usual weather lately. Could this be frostbite? What should I do? I'm really worried about her!
