I noticed yesterday that my almost 2 year old white Wyandotte was laying down more than usual and less active when she was up and about. She was free ranging with everyone else just more slowly. Her poop was also runny and yellowish, and when I checked her crop at the end of the day there was food in it. She went to bed like normal and when I went out at 5 this morning to check if her crop had emptied and help it empty in case it was impacted, she was already dead. Does impacted crop usually cause death that quickly or was it something else? She seemed normal the day before, so it happened quite fast.
