Chocolate Orpington enlarged crawl and throwing up

Squishy crop no poop since I found her about 3 1/2 hours ago

She finally pooped. I think she has a sour crop. She hasn’t thrown up for about 4 hours. I have been messaging her crop. She keeps acting like she is trying to regurgitate something.

She's not feeling too well

I would keep trying to massage the crop. See if you can get her to take a teaspoon of hardened coconut oil, then massage the crop.
If her breath smells bad, then it has turned sour and you will need to treat her for that.
The Nystatin that @Eggcessive recommended would be good. You can also read up on treatment options in the following 2 articles:
