Petaluma, previously known as the "egg basket of the world," has a hospitable climate for chickens: the air quality and intensity of the sun is perfect for promoting healthy egg production.

The longer the day, the more hens lay. In winter, when days are shorter, artificial light is used in the early morning and early evening to supplement the natural daylight, so that the hens will lay for a longer period of time.
