She looks sick. How old is she, and has she been laying eggs recently? Can you feel her crop and tell us if it is empty, full, firm, or puffy? When you feel of her lower belly, it is enlarged? Will she eat some chopped egg or tuna? I would mix some electrolytes and vitamins into her water, and get her drinking. What does her poop look like? I would be concerned that she might have worms or coccidiosis.
