Currently being a worry wort because one of my silkie chicks (5 weeks old) I think has sour crop. Originally we bought them this chick dust which they loved and ate right up. When I went to restock I got pullet feed which has bigger pieces, we just started feeding them this a couple days ago. I noticed one of the chicks seemed less hyper than usually so I picked it up and snuggled with it a little. The chick kept opening its mouth like it was trying to breath or swallow. I went to show the chick to the water bowl in case it was thirsty and this brown liquid came out when I tilted her towards the water. Immediately i freaked out and googled the symptoms on here and looked up what it might be. It was between impacted crop and sour crop. I felt the chicks crop and it was not "hard" per say but seemed a bit full. I massaged her crop and she began to burp up more brown fluids. During this time she became more vocal and began to peep, which I took as a good sign because she clearly wanted me to leave her alone. I'm not sure what to do, she still seems lethargic and not feeling her best but better than before. What are some treatments for sour crop and how can I nurse this sweet baby back to health?!
