Provide 14-17 hours of light per day for consistent laying

Ensure laying ducks receive 14–17 hours of total light per day by supplementing with artificial light during fall and winter when natural daylight drops below 14 hours. Use a timer to add a low-wattage LED bulb (9–15 watts is sufficient) in the coop, extending light in the early morning hours rather than the evening so ducks can still roost naturally at dusk.

Why It Works

Egg production is triggered by photoperiod — light stimulates the pituitary gland to release reproductive hormones that drive ovulation. As days shorten below 12–14 hours in autumn, duck egg production slows or stops entirely. Supplemental lighting tricks the hormonal system into maintaining production. Most duck breeds are more responsive to light supplementation than chickens and will resume laying within 2–3 weeks of light being added.

Tips

• Add light gradually — increase by 15–30 minutes per week to avoid stressing the flock
• Morning light is preferred over evening because a sudden lights-out at night leaves ducks unable to find their sleeping area
• LED bulbs are safest — incandescent bulbs are a fire risk in bedding environments
• Some keepers allow a natural winter break (8–12 weeks without supplemental light) to let ducks molt, rest, and rebuild nutrient reserves
