I ran into the "Chicken Doctor" at the ohio national poultry show. I just happened to have a sick hen, so i talked to him, he told me what he thought she had, and sold me some medicine. I recomend him for any chicken health issue you are not sure of. His site is http://www.firststatevetsupply.com/ you can call him or e-mail him. He is really helpful. I just think everyone should know about him. This should be a sticky!
