How does providing perches and dust-bathing areas for chickens relate to the Five Freedoms? Freedom from hunger and thirst Freedom from discomfort Freedom to express normal behavior Freedom from fear and distress What is a potential consequence of mixing unfamiliar groups of pigs? Increased feed efficiency Prevention of diseases Aggression between pigs Improved social bonding

Providing perches and dust-bathing areas for chickens directly relates to **Freedom to express normal behavior**. Perching and dust-bathing are natural behaviors for chickens. Perches allow them to roost, which is instinctive, and dust-bathing helps them maintain feather health and control parasites. Denying them these opportunities would restrict their natural behaviors.<br /><br />A potential consequence of mixing unfamiliar groups of pigs is **Aggression between pigs**. Pigs establish social hierarchies, and introducing unfamiliar pigs disrupts these hierarchies, leading to fighting as they re-establish dominance.<br />
