I have a Buff Orp chick that isn't doing well -- all the other chicks are all healthy and active. Her feathers have been puffed out, including around her head and neck, and her wings were drooping. This morning she seems to be ready to give up. Last night I offered her some feed (non-medicated chick starter crumbles from the local co-op) and initially she acted very hungry, but after taking one piece she wouldn't take any more. I doubt that she's had any water in awhile. I've brought her in the house to warm up, but I'm wondering what else I can do to maybe get her feeling stronger and able to fight off whatever this is. Any ideas about what this might be or what I can do to help her?
