HELP! 1 yr old silkie chicken problems

[Frostee]

I'm really worried about my 1yr old silkie hen. Her prolapse fell out so we took her to the vet. He said push it back in and keep seperate from the flock. We are pushing it in every 3 hours but she is not eating and I am getting very worried. Her crop is empty and food mostly untouched. Please help!!! I'm really worried about her, I love her soo much!
