A study has gained new insight into the minds of domestic hens, discovering, for the first time, that domestic hens show a clear physiological and behavioural response when their chicks are mildly distressed.
The study is the first to demonstrate that birds possess one of the important attributes that underpins empathy, and the first study to use both behavioural and physiological methods to measure these traits in birds.
The researchers used chickens as a model species because, under commercial conditions, chickens will regularly encounter other chickens showing signs of pain or distress due to routine husbandry practices or because of the high levels of conditions such as bone fractures or leg disorders.
