šŸ’” Light & Egg Production: Why Photoperiod Matters So Much
Want to understand why your hens aren’t laying as much or at all in winter? It’s not the cold - it’s the LIGHT! Let’s explore the fascinating science of photoperiod.
šŸŖ„The Magic Number: 14-16 Hours
Hens need 14-16 hours of light daily for consistent egg production. Less than 12 hours? Production drops or stops completely.
How It Works:
Light hits the chicken’s eye → signals the pituitary gland → triggers hormone release → stimulates ovary → egg production!
It’s a HORMONAL response to day length.
Natural Seasonal Cycle:
ā˜€ļøSpring/Summer: Long days = maximum production
šŸ‚Fall/Winter: Short days = decreased/stopped production
🐤This is NORMAL! Wild chickens don’t lay year-round - it’s their rest period
Supplemental Lighting Considerations:
If You Choose to Add Light:
šŸ’”Add in MORNING (not evening - sudden darkness stresses birds)
šŸ’”Use timer for consistency
šŸ’” Aim for 14-16 total hours (natural + artificial)
šŸ’” Gradual increases only (never sudden jumps!)
If You DON’T Add Light:
šŸ“Hens get natural rest period
šŸ“May extend productive lifespan
šŸ“More sustainable, less stress
šŸ“Production resumes naturally in spring
Important: NEVER add light to pullets under 20 weeks - can cause reproductive problems!
Your turn:
ā“Who is excited for the increasing day length?
ā“Anyone starting to see more eggs?
