Her eyes are bright and alert, indicating she isn't sick. Her posture is upright and normal, so she isn't in any pain. Her profile indicates a normal crop. What has her poop looked like?
What are you giving her to eat? Have you tried other foods besides her chicken feed? Have you smelled the feed? Does it smell fresh or does it have an unpleasant unusual odor?
Right now, try giving her one cup of water with one teaspoon of sugar stirred in. Dip her beak a couple of times to show her it's sweet. Let her drink as much as she wants. This will elevate her glucose so she will feel more energy, and it may restore her appetite. Start her off with some cooked egg.
