GreenTracker| British researchers believe they have verified for the first time that domestic hens show empathy and distress when their chicks are even mildly distressed.
The study by academics at the University of Bristol’s Animal Welfare group used both behavioral and physiological monitoring to determine results.
During one of the controlled procedures, when the chicks were exposed to a puff of air, the hens’ heart rate increased and eye temperature decreased. The hens also changed their behavior, and reacted with increased alertness, decreased preening and increased vocalizations directed to their chicks. via Science Daily
