What do you feed her?
The shaking is concerning along with the limited mobility. From what I can see, the poop looks o.k.
I would get her on some Poultry Vitamins that contains E, B2 and B1. Sometimes it can be hard to find that combination so you can use human vitamins instead. For vitamin E you can squeeze out 1 400IU capsule daily into her food and crush up 1/4 tablet of human B-Complex into her feed daily as well.
The crop not emptying completely overnight you need to watch that - soft foods and wet feed would be good, offer poultry grit free choice. You may want to massage her crop several times a day too so you can become familiar with how it feels.
