A low light intensity from 5 to 10 lux is required for production. The most important thing to achieve is the best uniformity of light spread possible. Standard light bulbs with dimmers are preferable to fluorescent lights that can be perceived as flickering by birds.
It is advisable to use higher light intensity at the start of production to stimulate feed intake. Once feed intake meets the desired level and the peak of production is achieved, light intensity can be decreased. There is a strong correlation between bird activity and
feather loss during production. Too high light intensity can encourage pecking and result in increased mortality.
