Egg-laying Flocks
FARM-PROTECT Egg Producer: overnight VOC monitoring for earlier insight into laying flock health
Egg-producing hens present a very different disease-monitoring challenge from broiler chickens. Broilers are reared over short production cycles, where rapid disease detection is critical to protect flock health before processing. Laying hens remain in production for many months, so health challenges can have a longer-term impact on welfare, laying rate, egg quality, shell strength and overall flock performance.
In egg production, disease or stress may not first appear as obvious illness. Early changes can show through reduced egg numbers, poorer shell quality, changes in bird condition, gut health problems, respiratory pressure, red mite burden or reduced flock resilience. Even mild or sub-clinical health issues can affect productivity over time.
Free-range systems add another layer of complexity. During the day, hens may be outside on the range, making flock-level air monitoring impractical. Outdoor VOC profiles would be too diluted, and the surrounding air would contain too many variable environmental compounds to provide a reliable disease signal.
FARM-PROTECT Egg Producer is being developed around this practical reality. Instead of trying to monitor birds outside, RoboScientific’s approach focuses on overnight air sampling, when the hens are safely housed and the flock is together in a more controlled environment.
By sampling the air in the poultry house overnight, the system can analyse volatile organic compound patterns associated with biological change across the flock. This creates a non-invasive way to look for early health signals without handling birds, disrupting normal routines or relying only on visual checks.
The aim is to give egg producers earlier warning that something may be changing in the flock, allowing closer investigation, veterinary input and management action before disease or stress has a greater impact on welfare, egg output or egg quality.
FARM-PROTECT Egg Producer builds on RoboScientific’s poultry VOC sensing platform, but adapts it to the specific realities of egg production: longer flock cycles, free-range behaviour, overnight housing, red mite pressure, egg quality, shell strength and the need for ongoing health surveillance throughout the laying period.
By turning overnight housing into a practical monitoring opportunity, RoboScientific is developing a new way for egg producers to gain earlier, non-invasive insight into flock health and protect productivity across the laying cycle.
A New Approach to Safeguarding Layer Flock Health Through Air Monitoring
Early disease detection is just as critical for egg-laying flocks as it is for broilers, but the pressures are different. Laying hens remain in production far longer, which means even mild, early-stage illness can affect performance for weeks or months if not identified quickly. Subtle health challenges can reduce lay rate, weaken shell quality, and compromise overall flock resilience long before visible symptoms appear. Because routine checks only capture what can be seen at a single moment in time, the earliest changes are often missed.
Air-based detection offers a new level of insight. By monitoring the air inside layer houses, the system can identify early signs of disease or stress before they manifest in the birds themselves. This is practical even for free-range flocks, which must be brought indoors overnight for safety—providing a reliable window for indoor sampling and automated monitoring without disturbance.
Egg-laying flocks also face a different disease landscape from broilers, including conditions and pathogens that require new sensor profiles. For that reason, dedicated sensor arrays are being developed and trialled specifically for layer environments to ensure accurate, flock-appropriate detection. Automated air collection, high-sensitivity analysis, and alerting systems combine to give producers an early signal when shed conditions begin to change, offering time to act, prevent spread, and protect ongoing egg output.
This approach provides a fast, non-invasive early warning system tailored to the needs of modern layer production—supporting better welfare, stronger performance, and greater protection across the flock’s full laying cycle.
