If you have a river near you get some sand from it to put in with them. (No salt water) is her crop squishy? Sounds like sour crop to me. Hears the treatment
Separate 24 hours no food only water with 1/4 teaspoon of acidified copper sulfate. (comes in powder form usually at feed store) in a gallon plastic waterer only. If you can't find that, use 2 Tablespoons of organic unfiltered apple cider vinegar in the plastic gallon waterer, changed daily.
Day two add only plain yogurt.
Day three add plain scrambled egg to the yogurt. Each day massage the crop, pushing toward the back of the crop, not upward.
Day four maybe some soupy oatmeal added to eggs & yogurt, but no grains.
Don't make throw up can kill them.
Hope this helps, best of luck.
