Winter Lighting For Your Chickens

 

Egg production tapers off when hens don't catch enough rays, which explains why many flocks stop producing completely in winter. 

A little mood lighting inside their coop, however, can help compensate for the shorter days. Just be sure to select bulbs that cast a warm glow—as the chandelier shown here does—since bluish-white light won't trigger laying.
