I always take a head count when I go out to feed, but I guess I didn't notice that one little cutie was sick. I don't know if her illness diverted blood from her feet and killed tissue, or if it's genuine frostbite. She's weak, sneezing like crazy, and off feed. Well, she did start eating again, after a week. Her toes are a black/red, and they seem to hurt her. She can't perch, and she doesn't move around much. It's been about a week since I've noticed her condition, and I believe the toes will be lost. I thought it would be interesting to document the process. The black part is getting skinnier, the way the end of a cut flower will shrivel I'll take more pictures when I see the process advancing.
