Chickens have complex behavioural needs including dustbathing, perching, foraging and social interaction. Enriched environments allow expression of these natural behaviours and improve welfare significantly.
Behavioural deprivation is a form of suffering. When chickens are prevented from dustbathing, they perform vacuum dustbathing on bare floors — a clear indication of thwarted motivation. Providing even simple enrichments like scattered substrate for foraging and perching poles measurably improves physical and psychological welfare.
