ONCE is back in the UK, this time in Mid Wales, where free-range producer Martyn Langford manages an impressive 64,000 hens. Known for his philosophy that “every day is a school day,” Martyn is always looking for ways to improve bird welfare and performance. That mindset led him to upgrade his newest multi-tier shed with NatureDynamics, ONCE’s connected, dynamic lighting system.
Lighting That Follows the Science
In the video, Martyn shares how NatureDynamics has transformed flock management through strategic spectrum tuning. By reducing white light and increasing red wavelengths, he’s seen clear improvements in:
-
Behavioural control
-
Feather cover
-
Overall bird management
One of the most striking results?
Floor eggs are significantly lower in the NatureDynamics-equipped shed compared to his other sheds, an important indicator of improved movement, comfort, and environmental familiarity.
Martyn also reports more consistent light distribution, which has:
-
Improved bird flow throughout the shed
-
Enabled more even occupancy
-
Supported smoother daily management
Because Martyn operates four sheds, he can directly compare results. The verdict is clear: NatureDynamics delivers measurable, practical improvements in both flock behavior and performance.
