Our favorite hen has severely swollen wattles and can't open her right eye. She wheezes off an on, but not constantly. She does have two small punctures on her wattles (we have snakes out here...is it possible for a hen to survive a rattlesnake bite???!) and one small cut on her crown (she is often picked on by the rest of the flock). She is fairly alert and drinks water when offered to her. I haven't tried to offer her food yet. Thanks for the advice on what to do!!
