Which environmental factor is key to keeping a flock of laying hens producing eggs year-round?

Light is a crucial environmental factor in maintaining year-round egg production in laying hens. Hens require a specific amount of light each day to stimulate their reproductive cycles. Typically, they need about 14 to 16 hours of light exposure per day to maintain optimal egg production. This light exposure helps regulate their hormonal cycles and encourages consistent laying.

In commercial settings, artificial lighting may be used to extend daylight hours, particularly during shorter days in winter, ensuring that hens continue to lay eggs consistently. In contrast, while temperature, moisture, and humidity are important for the overall health and comfort of the flock, it is the light levels that directly influence the hens' egg-laying rates. Proper light management can lead to improved production and better overall flock performance.
