We previously found that applying a light schedule during the early brooding period (0-4 days post-hatch) of a broiler chicken influences leg bone development at D4, in favour of the continuous light treatment. In the current study, effects of light schedule and transition from light to darkness (abrupt or gradual transition in 15 minutes) from D0 to D4 on leg bone development and body weight until slaughter age were investigated.
