Dust bathing is a fundamental behavioral need for chickens — one that most commercial systems fail to meet.
Dust bathing is not a luxury but a behavioral necessity for chickens. Hens deprived of loose substrate for dust bathing show vacuum dust bathing — going through the motions in the absence of material — demonstrating how strong the drive is. Providing adequate dust bathing opportunities reduces feather pecking, improves feather quality, and allows chickens to express a fundamental natural behavior. This is a low-cost welfare improvement with significant behavioral impact.
