Swollen crop....general question

[Tmatthews]

After doing much research on here, I think my hen that just died recently, died of something related to her crop. She was sluggish many days before she finally was just laying there and ended up dying. Other than being lethargic, her only other symptom was a slightly enlarged crop and it felt squishy. When I handled her and massaged it, she threw up a great deal. But being as stupid as I am, I figured it was because she was just sick. Now after reading posts on it, I think this was the issue. I was just wondering why this causes death?
