My 9 month old GCC Kiwi has started barbering her tail feathers. She had previously barbered her clipped flight feathers, but I was told it wasn't something to worry about because she was likely doing it because they didn't feel right. But today I came home and she's barbered one side of two of her tail feathers. Now, she only has two full length tail feathers because she keeps breaking them while trying to fly (I can't wait for her flight feathers to grow out). I'm really concerned about this behavior, she's still a baby and I want to stop this now before it gets any worse. Any suggestions would be great!
