Okay, I've been reading the posts on the impacted crop. When do you decide you need to do the surgery? My Diana's crop is soft and massagable, but she is still spitting out sour gunk and occasionally grass or grains. I have held her upside down and massaged junk out twice and her crop goes down. Then she drinks a lot of water and begins to spit out the junk again. She is not eating, but I can get her to drink. Have been treating her for two days.
