I researched. They are in a chicken tractor, so on the ground daily. She would stretch her neck out to gasp for air and then put her head down eyes closed, looked like she was dying. She would hiccup, like a loud screech every now and then. And before she died she was thrashing her entire body all over the pet taxi I had her in. She wouldn't eat or drink. I thought she maybe had something in her throat, but I looked and saw nothing. I tried to make her vomit, nothing. Crop was empty. No discharge from eyes, nose, or mouth. Rattled breathing. She was gone 20 minutes after I noticed her symptoms.
