Is her beak damaged on her right side, or does it look normal to you? It almost looks fractured. She looks lethargic and weak, and her wings are hanging while she is standing puffed up. What does her poop look like? I would think that she might be very dehydrated and possibly have coccidiosis, just from her appearance, but her beak concerns me. Can you get her drinking some water and put some watery feed in a bowl to see if she will take some? I would be tempted to bet some Corid right away and treat your chickens. How old is she?
