Avian influenza outbreaks require companion bird keepers to implement housing measures that can significantly compromise bird welfare, creating tension between disease control and normal husbandry.
Avian influenza biosecurity requirements create a genuine welfare dilemma for companion bird keepers. Housing orders requiring birds to be kept indoors protect against infection from wild bird contact but impose welfare compromise on birds adapted to outdoor life. Companion chickens, ducks, and geese kept permanently indoors may develop behavioural problems from confinement, lose access to natural foraging behaviour, and in the case of semi-aquatic species like ducks, lose access to water for swimming and preening. Extended housing periods - sometimes lasting months during high HPAI risk seasons - cause progressive welfare deterioration as birds adapt poorly to confinement. The welfare trade-off calculation must weigh the acute welfare harm of HPAI infection (high mortality, systemic disease) against the chronic welfare harm of extended indoor confinement. Keeper responses that maintain welfare during housing orders include maximising enclosure quality, providing foraging enrichment, ensuring adequate light levels, and providing ducks with water containers for head-dipping even when outdoor ponds are inaccessible. Disease risk assessment tools from APHA help keepers understand when risk is highest and housing most important.
