If she is losing weight, then she will benefit from being kept in a warm environment as the lack of food going through her system will mean she has nothing to maintain her body temperature, especially now that we are heading into cooler weather.
How often are you massaging and have you removed access to everything except liquid food that would pass through a kitchen sieve.... ie no lumpy bits?
Make sure she has no bedding that she can eat.... puppy pads are best for them when they are impacted like this as their poop is usually quite runny, so the pads absorption helps.
People whose experience I trust here on the forum have recommended solid coconut oil given to the bird in small chunks and then massaged.... as much as a teaspoonful at a time.
Sometimes it can take many days to break up an impaction like that. It took me 10 days of massaging to clear one of my bantam hens and another pullet was still huge after 2 weeks of massage and I had to do surgery on her. It was amazing how quickly she recovered after the surgery...... she was running around within minutes of gluing the incision closed (super glue is wonderful stuff) and happily wolfing down scrambled egg 30 mins later. She was back up to weight and laying me an egg exactly 2 weeks after the surgery. Can I just mention that the anaesthetic can be more dangerous than the surgery with chickens and crop surgery can be performed without anaesthetic. It seems a bit brutal but my girl coped with it incredibly well and recovered far more quickly for not having been sedated. Just something to bear in mind and perhaps discuss with the vet if it comes to that or there are You Tube videos which show you how to do the surgery yourself which helped me enormously.
I am told that a stool softener like Dulcolax
without stimulant is worth trying before opting for surgery, so that might be something else to add to your list of pre surgery options.
Something else to consider is that the blockage may be lower down her system than her crop. Reproductive problems in hens over 2 years are common and can cause their digestive system to get stopped back and exhibit as a slow or impacted crop. Usually in such cases there will be some abdominal swelling either between the legs or below the vent which can be felt by cupping your hand between their legs from behind. Comparing with a healthy hen is important so that you have an idea of what normal feels like. Hens suffering from these ailments will often have soiled butt feathers or bald butts from excessive preening of soiled feathers. This may not be applicable but just something to check.
Good luck with her. I hope you are able to fix the problem. Please let us know how you get on and hopefully what works with your girl.
