The first days of life are critical for broiler chick welfare, with temperature regulation, nutrition access, and social stress determining long-term health and productivity.
The brooding phase - the first two weeks of life - establishes the health and welfare trajectory of the entire broiler flock. Temperature stress, dehydration, and delayed feeding cause immediate suffering and long-term immune and growth impairment. Hatchery practices including delayed placement and long transport journeys extend the period of deprivation after hatching. Best practice requires rapid placement with immediate access to water and appropriate starter feed, correct temperature gradients, and attentive stockmanship during the first 72 hours when chick mortality risk is highest.
