Litter quality in broiler chicken houses directly affects footpad health, and footpad dermatitis is one of the most reliable welfare indicators in commercial poultry production.
Footpad dermatitis in broiler chickens is a welfare indicator that captures the cumulative effect of housing conditions on individual animal health. A chicken with severe footpad lesions is in chronic pain that affects every aspect of its daily life -- moving to food and water is painful, so the bird rests more, eats less, and grows more slowly. The management factors that drive footpad health are known and controllable: litter moisture, drinker design, stocking density, and ventilation quality all independently predict footpad lesion severity. The fact that footpad scoring is mandatory at slaughter in the EU makes it a measurable, actionable welfare standard -- the challenge is acting on the data rather than recording it.
