I haven't read through all the pages but I had a turkey that was sick once like this. He stood with his head down towards his chest and he had really yellow/green smelly poo. I'm convinced we would have lost him but some people on here suggested cayenne pepper. We went nuts with it in the water and food and within a few days he did get better.. and he's now a healthy turkey who's currently outside strutting his stuff to his female and gobbling away.
