Dust bathing is a fundamental behavioral need for hens that is routinely denied in conventional cage systems, causing chronic frustration and poor feather condition.
Dust bathing is not optional for hens — it is a deeply motivated behavior driven by internal biological rhythms. When denied appropriate substrate, hens attempt to dust bathe on bare wire, a frustrating and ultimately ineffective behavior that indicates significant psychological deprivation. The cumulative frustration of being unable to perform this behavior daily represents a serious welfare harm. Cage-free and free-range systems that provide adequate litter substrate allow hens to meet this fundamental need.
