I'm not a vet, but would have to say that your hen has Salpingitis (see the links and information in my previous post).
Unfortunately, there is not any real treatment for this. Sometimes antibiotics can help with infection, but usually when you start to see symptoms and poop like that the infection has taken over. You can ask your vet if they would recommend any medication that may help her. Supportive care would be to see that she is drinking well and eating. Add poultry vitamins to her water for a boost. If she stops eating/drinking or becomes lethargy and won't walk/move, then it's kinder to put her out of her misery.
