I just lost a special hen myself. We don't know what it was either. My mom always reminds me that our birds are incredibly lucky being treated well and able to roam free, interact with humans and other animals, living as nature intended. I can see that you take wonderful care of yours too. Killer was lucky you adopted him. Just try to remember that in the short life that he had, he was a very happy, spoiled little rooster. I am sure he loved you for that
