I agree with
@NanaK the poop is not too terrible, I've seen worse.
Green can sometimes be bile from not eating very well.
I prefer to have them eat their normal feed (wet or dry) and give egg to eat to entice them. Other things that I've found are tomato, watermelon, cucumber...often these are interesting.
I try to keep them eating things they normally eat, just cutting back on things that may be a bit harder to process (like scratch, seeds, etc.). BUT, if you feel she needs baby food, some people certainly syringe or tube that into them. Some use Baby Bird Formula as well.

@NanaK says, we all do things a bit differently. Seeing her at least participating and moving about is good. She's still not there and chickens can often continue to interact in order to hide not feeling well so the flock doesn't notice so much.
I'd finish the Corid and Nystatin. What is the crop feeling like in the morning now (before she's had anything to eat/drink). You can try 1 more stool softener, but if there's material in the crop not moving and you've given the softener for a couple of days, it's likely not going to break up a lot more.
See how it goes tomorrow.
