I just added some pictures for you to look at. I checked her crop this morning and it feels full. Not sure what to do now.
I also just checked her belly and between her legs and my instinct says she has an egg stuck maybe. I think I will try the epson salt bath and see if that helps.
I'm sorry she is still not feeling well.
Her stance does remind me of a hen that is having reproductive problems. Checking her to see if you can feel an egg is a good idea.
She may have an internal laying problem, but a soak won't hurt her. I would also keep her drinking. Crop problems are often a symptom of an underlying condition, so I treat the crop too.
