Feedback needed on dick chicken

Since 3 days one of my girls is slow. She was walking with the other's around the garden and scratching but not as lively as before. This morning she just stood a little around under the coop so I wanted to get a better look. When I lifted her up, I tilted her a little and water came running out of her beak. I expected an impacted crop so I inserted water and massaged the crop. Yellow water came out together with something that looked like plastic or a balloon.

Since then, she drank a little water, ate almost a full boiled egg and had some Swiss chard. I put her in the garage in a box with straw to monitor if she poops but so far she is standing not sitting. She is standing normal, not like egg bound chickens. She is not molting, I couldn't see any parasites and her cloaca looks normal.

is there something else I can do or should I just wait at this point?
