Give two docusate sodium 100mg capsules this is a stool softener which you can buy at any pharmacy , followed buy 4cc of red wine which acts as a laxative and helps move things along , this will not harm your hen and is non toxic , provided a slice of watermelon for added hydration and give this asap then cheak your hens crop next morning if its still impacted give another dose also give another dose to her just before bed and I assure you he crop will go down eventually but it can take up to four days. Sometimes if an innpation is sever , please don't try to vomit your bird as it won't help and can kill her buy accidental aspiration , don't give apple cider vinegar as it will agravate this condition and make you hen develope sour crop , do give a probiotic capsule to her or buy probiotics for chickens an excellent one is called big ole bird made buy southland organics , massage her crop several times per day in a downward motion , good luck to you and let me know how it goes!
