Description
Eunji Park and Juwhan Song build an early warning system for dead chicks on broiler farms, in a 2026 study. A dead bird looks much like a deeply resting one in a single camera frame. Their pipeline instead measures how long stillness lasts. Ceiling cameras filmed a commercial flock of about thirty thousand young birds. A detector located each chick, and a sequence classifier labeled eight-frame clips as stationary or moving.
Stillness durations from over ninety-three thousand normal observations set candidate alarm thresholds. Stricter thresholds traded a little speed for far fewer false alarms. A conservative cutoff flagged deaths with precision near ninety percent on a fresh month of data. Alarms fired roughly eight hours before workers would remove the birds by hand. The authors argue death detection is a timing problem, not a shape problem. Farms could adopt the approach to speed carcass removal and cut disease spread.
