My EE frizzle hen Twilight is the prettiest hen in my flock. But a while ago she began losing feathers in odd places. It started out on the head and back, this led me to believe it was Twinkle the rooster, Twilight's brother. I was going to get her a hen apron before I actually saw Twinkle mount her. He did not do any damage to the feathers, and his foot placement was not anywhere near the missing feathers on her back, which gave me some doubts. Soon I realized her beard feathers were gone, and later her entire neck became bare. Even feathers around her cloaca have been falling off recently. I know one thing for sure, SHE'S NOT MOLTING. I know this because, despite all this, she's still laying healthy eggs. AND, her brother Twinkle would be molting too because they are the exact same age. I have never heard or seen anything like this, ANY IDEAS? There was a beautiful beard on that face.
