Adding Lights to Increase Egg Production

Lighting Laying Hens:

Allow chicken coops to have 14-16 hours of uninterrupted light a day (18 hours max).
It is best to add extra hours of light in the morning to your daylight timer (so the lights come on earlier). Be sure to frequently check the accuracy of your timer for best results.
The light should be about 1 foot candle (40 watt equivalent) for a 10’ x10’ coop at bird height. (Enough light to read typical newsprint).
Lights in the red - orange spectrum range are the best for egg production
Install two bulbs in case one bulb fails before you notice.

Terms to Remember:

Duration -how long light is perceived
Intensity -how bright light is perceived
Wavelength- color of light
