Light levels (intensity or illuminance) and the duration of light (photoperiod) are important factors in poultry production. Intensity has an effect on cannibalism and aggressionI along with feed and water intakeI while photoperiod influences reproductive and egg production cyclesI total feed intakeI and growth rate.
Chickens perceive light (colours) in a different way from humans who can only recognise red, blue and green colors. In chickensI the eye is one of the most highly developed sensesI enabling chickens to perceive more colours. Chickens also have an extra sensitivity peak in the ultraviolet wavelengthI which enables them to recognise each other better. If chickens cannot recognise each other they will peck their companions and this will disrupt the pecking order.
