One of my church's chickens is sick. She is a 4-5 month old Americana. She has a crusted over nose and is coughing- wet sounding. I can hear her breathing. She has diarrhea and is very skinny. Her left eye is closed and the area around it feels soft to the touch. I can bring her to my vet but I know that she will want to refer to here as how to treat her. I bought her from a breeder in Western GA about two weeks ago and she was not showing any signs of sickness at the time. Also I was told that someone else may have given her a Tylenol- we do NOT give this medication to dogs and cats so I'm assuming that it's toxic to chickens as well.
