Two days ago I noticed my favorite OE had a large crop and was very lethargic. I did some internet research and found that she may have sour crop so I massaged her crop upward towards her head and she vomited a very smelly discharge with a little grass. This morning she seemed better, but when I touched her crop this time it felt like it was full of food, but still very large. I confined her to a private space and left her there for the day. Can anyone tell me if I am handling this properly? Tomorrow morning I will check on her again and give her some yogurt and fresh water. Any advice is greatly appreciated. Thank you.
