Help :((

It’s been weeks.. and my chickens crop still feels pretty squishy. I gave them vet rx, coconut oil, olive oil, yogurt, layer feed, water, and apple cider vinegar and nothing works. They seem to get bit better like more active but idk why the crop is squishy still. Like in the morning when there’s no food inside it feels squishy but empty. But when it’s full, I can feel the food in there and the crop is squishy. Is it just the chicken fat or I’m not sure... I’m pretty worried. I’m trying to find flint grit for them and I gave multipurpose sand too

As mentioned in your other thread, I would treat like Sour Crop. I understand your parents don't want to get medication(?) but it would be helpful to do that.
