First of all I am so sorry you lost Sundance someday you Will meet again!
When I first got chickens I put in an automatic door, the gang was very good about getting in before it shut. Well, one night my rooster stood in the doorway pecking at something at the top of the ramp and I watched in horror from inside as the door came down on his skull I ran outside and he had manged to get loose but his eyes began bruising and swelling, his whole head did and he passed away. I think he suffered a skull facture which caused brain swelling.
Sorry I got so discriptive, just thought I'd let you know.
And again I'm very sorry you lost your friend,
