Recently I had a Cream Legbar hen come down with impacted crop that was also full of yeast infection. It had a putrid sour odor that smelled like a backed up garbage disposal.
First of all, I worked on the impaction by introducing coconut oil into her crop at intervals, about a teaspoon at a time, massaging her crop after each time. Finally, I gave her a stool softener capsule and let it go to work. I gave her another crop massage a few hours later, and felt the mass break up under my fingers and go down. This process took all of one day to accomplish.
Then I addressed the sour crop issue since the smell told me in no uncertain terms that is what I was also dealing with. I gave her miconazole twice a day for seven days. I used the cream version, about a quarter to half inch of cream on my finger which I slipped into her beak.
She recovered fully and is now the picture of health.
