Does anyone have a recommendation for an anti-fungal medicine for sour crop? I can't get my girl to eat any yogurt and plan on using a dropper with yogurt on her tonight. Anyhow, I'd like to have some medicine to give her and have on hand in the future. I've had her quarantined with no food for 36 hrs and her crop is still large and squishy and her breath is horrible. She was eating before I quarantined her and now she isn't. Still drinking water though. I've been massaging her crop a few times a day and there feels like there is something very large in there. Is there anything else I can do? I don't feel comfortable vomiting her.
