I have been reading through the thread on treating sour crop with monistat: https://www.backyardchickens.com/t/630307/sour-crop-cured-with-monistat ....and I am wondering if someone can clarify. Am I understanding correctly that sour crop happens after a crop has been partially impacted for some time, and the stuff that's stuck in the crop has begun to ferment? If so, then wouldn't you need to remove the stuff that's stuck in there, for the bird to fully recover? I can see that the monistat would kill the fermenting fungus, but I would think that sour crop would just recur, if that stuck material is not removed. Am I thinking about this correctly? Or maybe I have it backwards: Is it the fungal infection that's causing the crop to malfunction and not pass all the food downstream? If that's the case, then it seems like treating the infection with monistat would actually help the chicken to pass the impacted material. The reason I ask is that I have a bantam brahma hen with a huge, firm crop that is virtually no smaller by morning. She still eats and poops and looks OK other than the huge crop. Does this mean she has sour crop, and is monistat likely to help her, or do I just need to get her to pass the impacted stuff???
