What is a common sign of good health in chickens?

Bright, clear eyes are a definitive indicator of good health in chickens. Healthy chickens display bright and clear eyes, which suggest alertness and vitality. This characteristic signals that the chicken is engaged with its environment and not suffering from illness or distress. In contrast, signs such as fluffed feathers, lethargy, and hunched posture often indicate underlying health issues. Fluffed feathers can suggest that a chicken is cold or unwell, lethargy indicates a lack of energy and could be a sign of illness, while a hunched posture often reflects discomfort or pain. Observing the condition of a chicken's eyes is therefore crucial for assessing overall health.
