We've had Norman for 2 years now. he is free range and even though he's slow he's been doing well. All of a sudden in the last couple of days he seems to be out of breath and tonight when I checked on him he looked purple. He doesn't have feathers underneath and he's bluish/purple. I realize he may be at his end of days but, wondered if I can help him at all? Please be nice.. we kinda love him.
