What is the ratio for a horse breaking its neck in a hay feeder? - horse hay feeder

I work in a company for an internship, and only on Friday, 20 March 2009, a Shire years and 8 months in the dead Heulader. He said he broke his neck. Never heard of this happening before and I was wondering if anyone with some answers, how much time has elapsed, or if it came before the incident.
