Fordguy - you should start a new thread for your hen. You will get more responses that way. You also could be more specific with her signs of illness. How old is she? Does she lay eggs? Is she still laying? Is she eating/drinking? Is there food in her crop? What do her droppings look like. Any sneezing or nasal discharge? Most birds who are sick will be lethargic and looked "puffed up". It could be anything but we need more info.
