We purchased chicks from a local farm. They are approximately a month old. Last night when we did our bedtime check, we found our mottled java chick, who had appeared incredibly healthy and vigorous up until that point, Laying stretched out. She was unable to stand and was listless. Within a matter of minutes she flapped her wings suddenly, chirped once and died. We looked her over carefully and could find no evidence of injury or pasty butt. Has anyone else had this experience? We are mystified!
