Hi! I went to give my Belgian d'anvers water and noticed one of the hens (Lucy) was standing quietly in the back while the other hens ran up to see what I was doing and get a drink. I picked her up and her crop was very hard and slightly enlarged. Then what really freaked me out was she was twisting her neck in weird jerky movements. She pooped twice but she won't eat or drink. My mom thought she ate way too much and she'll be better soon but I worry so I wanted some other opinions. Right now she's separated from the rest of the flock and I've massaged her crop and that seemed to help as now it's a little softer. Does anyone have any ideas on how to help?
