Abstract

In the present study, it was found that older poultry preferred to be in dim light (6 lux) when inactive but in bright light when they were active. Some variation in ambient light intensity to provide both dimly and brightly lit environments might benefit the welfare of poultry aged more than, say, 4 weeks old.
