We have a three year old sweet hen with confirmed sour crop. She didn't eat anything yesterday and didn't eat anything today. We have her on Fenbendazole, Corid and now Micanazole started today to cover every base. She has been having issues for a while but now in the last 48 hours developed sour crop. Anything else we can do to help her. I fear that with no further intervention she is going to die. Any suggestions or ideas on how to treat her aside from what we have already done?
