Not sour crop - doughy crop to fluid filled and not emptying - ADVICE PLEASE

[Equiem]

Prudence is my one original ex-battery hen that has never had to go to the vets... yet!
She is 13 months free after being rescued from slaughter in March of 2018.
I am in the UK and she is one of 6!

Background:
Thursday morning, she was slow to come out so I caught her (much to her disgust - she hates being held) checked her over and noticed her crop was waltnut sized and very doughy. I know this is common after a bought of sour crop because I have dealt with it before however she has never shown any signs of this - no big ballooned crop and no foul smelling liquid or odor coming from her beak.

I separated her off, let her have access to water but no food in hopes that the crop would empty in this time so I could use the anti-fungals as it works best on an empty crop. Unfortunately, her crop didn't empty so I turned to the internet for advice.
I have given her 2 doses of nystatin that I had left over (still in date) from a previous chicken. I gave her access to kefir and live yogurt and then some soggy mashed pellets. I have also given human oral thrush medication (Daktarin) to her in hopes that it will help as I have seen it suggested on another forum.

Anyway, the doughiness went away BUT her crop now isn't emptying of some sort of fluid. It is still not ballooning or foul smelling so I don't think it is sour but it will not shift and this has me worried. She went to bed with it last night and woke up with it this morning and it is still there this afternoon. She is withdrawn, not showing interest in eating and is not her usual bullying self. I have massaged it and feel a few little pellets/corn and can feel no obvious obstruction. Vomiting her is a last resort as I do not feel confident and do not want to make things worse for her.

Their food is in date, the food in the feeders is changed regularly and the feeders are bought in every night. I plan on calling the vets in the morning to see if I can get an emergency appt with the chicken vet or at least some advice from her!

This is just something I haven't ever come across and I'm wondering if anyone has any experience with a crop issue like this or can give any advice! It will be greatly appreciated. I'm worried for her and I'm going completely out of my mind about it!

I'm so sorry your hen is ill. I think that the vet is your best bet for determining what may be going on. I've had quite a few with reproductive problems, like salpingitis, internal laying, or cancer, and this was a symptom. The underlying illness causes the digestive tract to slow down or even stop. Even if I was able to get the crop cleared, it would recur.
I hope you can get answers from your vet, best of luck to you.

Thank you!
She is still laying eggs regularly (I know it's her because she's been separated in a coop/run) so I'm hoping it's nothing reproductive but I know this can be the issue. With my last sour crop/doughy crop issued girl that I was worried about EYP. Luckily the vet aspirated nothing from her abdomen! I will try what I can within reason with advice from the vets. I just hope I can get an appointment!
