My hen isn't eating

[SCinCO]

My 2 year old Speckled Sussex stopped eating yesterday afternoon.
She is just standing. She will walk or run if necessary. She doesn't seem hunched and her tail is up like normal.
I have not been able to see one of her poops. Trying to get her to go on a paper towel.
Her crop just feels empty. I did see her drink some water earlier today. I tried a couple different treats to tempt her, but she won't have it.
She laid yesterday, but not today.
I know it's not much to go on, but any advice is welcome.

I did finally get a poop picture.
I gave her a soak, and made her drink some Gatorade from a syringe.
I don't really know what else I can do for her.

Are you keeping her inside tonight to keep an eye on her? Can you feel of her crop, and tell us if it is empty and flat, full and puffy or hard? Do you have any poultry NutriDrench or similar vitamin with electrolytes to give her a few drops? I would put on a disposable glove and insert a finger 1 inch inside to feel for a stuck egg. If you feel an egg, let us know. At that point I would give a human calcium tablet or Tums. Some things to try to get her eating which usually work with my sick hens are soft chopped scrambled egg, chicken feed made wet with water, tuna, canned cat food. Fluids are more important now. Holding a small cup or a spoon to the beak sometimes will get them to drink.

Yes she is inside. Her crop feels empty.i don't have poultry nutridrench at the moment. I syringed some gatorade. I tried egg, sunflower seeds, moistened bread, and moistened chicken food. I felt beneath her and she does not feel bloated. I didn't check inside for an egg since this started yesterday afternoon and she laid an egg yesterday.
I have seen her drinking water several times today.
