Sour crop assistance please and thank you

[Cara83]

My buff has sour crop and water poop.
I have confined her to the garage and withheld food for over 24 hours almost 36 now,she is still drinking. I have given regular crop massages, given nilstat and her crop has gone down somewhat and she has passed some grass.
When is it safe to give her some soft food like scrambled eggs, yougart mashed banana.
I have also tried some digestive enzymes to break down food in her crop yesterday and given coconut oil.
She is my favorite hen so would like to know if anything else I can do. Sorry for photo.

I'd continue with the anti-fungal for a full 7 days.
Introduce a little wet feed, egg, etc. in the a.m.

Does she have grit available?
