Stress in birds can be caused by various factors. Changes in the environment, adverse weather conditions, or large temperature fluctuations, high humidity, poor ventilation of the area, and sudden changes in the composition of food are some of the factors that lead to stress. Additionally, illnesses, attacks from predators, sudden loud noises that may cause terror, and cohabitation with other birds with dominant characteristics and tendencies to impose within the flock can contribute to this condition.
