Litter quality in broiler houses is a primary determinant of foot pad health, respiratory welfare, and behavioral welfare, with wet litter causing widespread painful hock burns and pododermatitis in intensively housed birds.
Broiler litter welfare illustrates how management decisions cascade into welfare outcomes through environmental quality. Wet litter from inadequate ventilation, drinker spillage, and excessive stocking density creates a habitat that causes chronic foot pad lesions — painful skin and tissue damage on the feet and hocks of birds that spend most of their time on the litter surface. Foot pad scoring is both a direct welfare indicator and a reliable proxy for overall husbandry quality because it reflects the cumulative impact of stocking density, ventilation, and water management simultaneously. Consumer welfare certifications that require maximum foot pad lesion prevalence thresholds create accountability for litter quality that production incentives alone do not generate.
