I have a hen who has had sour crop for about a month. I was desperate and started giving her Monistat and it seems to be working. We had the first semi solid poop in 2 months and she has been a lot perkier. But it seems now after a week her crop is back to squishy and sour. It seems to have stopped emptying and is full in the morning again. I have been massaging which helps some and continuing the Monistat. I am giving 1ml of the 2% cream twice daily. I read on a thread they did 3 times daily so maybe I'm not giving her enough. Is sour crop really hard to get rid of? Does anyone have knowledge of why it keeps going back and forth between sour and impacted not emptying?
