We lost one of our girls today. I did not see any trauma to her. She appeared to have been dead for awhile. She had her head and half her body in a wooden box. Like she was trying to hide. She wasn't even a year old yet. Their (our flock) diet has not changed. And the temps haven't been that bad, cold wise. I know there are countless reasons. I'm just curious. Never had a young bird die like this.
