Rosie got spooked and hurt herself by flying into a window and lost most of her flight feathers on her right wing about a year ago, and they haven't grown back. It was bleeding, but only a tiny, barely noticeable, spot. I thought she would be fine and her feathers would grow back, but she still holds up her wing like it hurts sometimes and no new feathers have grown back. She can kinda fly, or glide, (lets just say she can get around,) but she can't fly anywhere near as graceful as tweety. I called to see how much it would cost to take her to the vet and it's terrifyingly expensive! Does anyone know why her feathers aren't growing back? And is there anything I can do to help her?
