Mylanta or Maalox is helpful with sour crop. It is my first choice for treatment. Additionally, when dealing with sour crop, withhold all food until the condition clears up.Thanks, countrygirl. The crop is squishy and her burps stink so I think it's sour crop. I stopped trying to get her to spit up after the first day. It wasn't productive and then I read more about it and how dangerous it can be. I'm just massaging now. I'm doing the recommended treatments listed (isolated, acv, probiotics). So far, nothing has been helping. She's already lost weight. I went to Walgreen's last night about bought some anti-fungal cream (monistat, and was that ever embarrassing!) and gave her some of that last night and this morning. I'm keeping my fingers crossed that she'll pull through. It's a bummer that I'm having a health issue so early in my chicken keeping.
