I would check her crop first thing in the morning, before she eats or drinks, to make sure that it has emptied. Has she lost any weight in her breast area and is her keel (breast bine) bone prominent? Feel of her lower belly between her legs to check if it is enlarged or tight. Can you call you local vet to see if they will test her droppings for worms and other parasites? If you can give her some probiotics for the next week, and a little cottage cheese or cooked rice with buttermilk, it might help her diarrhea.
In one picture she looks like she is standing more upright. Is that obvious to you, or just the picture? Reproductive disorders can be common, and there can be a number of symptoms including a bloated belly, runny poops, waddling, walking upright, not laying, and weight loss. It can take time coming up with a diagnosis, and it has to be hard on you to keep her separate. Hopefully, we can help you figure out what is going on.
