Sour Crop Without Sour Smell? Lethargic Hen

[Barredbuzzard34]

Today and yesterday she has been losing her appetite a bit. Her crop is nowhere near as full as it was when she first got sick. Water does seem to drain from her crop every day and there are no hard lumps or anything that I can feel. She doesn't seem very interested in food, but she won't stop drinking water. We are hesitant to let her drink her fill because it seems really excessive for a chicken. She will drink for several minutes straight, or longer if we let her. If we let her outside, she mostly stands and sleeps, but will wander sometimes, especially if she can see her water cup. She has crossed the entire garden at grandma speed just to get more water. She also hasn't really passed any solid poops despite having eaten a good amount of food a few days ago, plus a bit more yesterday. Her poop is super runny, and sometimes has those tiny green logs in it like you see from chickens that aren't eating. Her tail is almost always down and she often doesn't even hold her wings up. Not sure what else to do for her. Does this seem like coccidiosis?View attachment 2098984

She just passed away. No idea what the matter was. Wish I could have helped her...
