Why don't you go ahead and search "sour crop" here. There's different listings, you can see what people did to fix it, if it came out ok, etc. If she's getting better, I don't think sour crop is a condition that will kill her.I'm trying to figure out how to get a picture of chicken anatomy posted here. I wonder if "sour crop" mean like when we have sour stomach/heartburn, or it just means too much stuff in the crop?
