PART 2General additional conditions

Light4

All buildings must have—

light levels sufficient to allow all hens to see one another and be seen clearly, to investigate their surroundings visually and to show normal levels of activity and where there is natural light, light apertures must be arranged in such a way that light is distributed evenly within the accommodation; and

b

after the first days of conditioning and to prevent health and behavioural problems a lighting regime that—

i

follows a 24-hour rhythm and includes an adequate uninterrupted period of darkness lasting about one third of the day, so that the hens may rest and to avoid problems such as immunodepression and ocular anomalies; and

ii

provides a period of twilight of sufficient duration when the light is dimmed so that the hens may settle down without disturbance or injury.
