Moisture Matters: Unveiling the Impact of Moisture on Layer Performance
In the world of layer production, temperature and feed management often take the spotlight as the most critical elements. However, there is the important consideration of water management that will determine the health and performance of your layer flock. If left unchecked, excessive moisture can turn into a silent yet potent adversary that hampers the success of your production.
Whether it's the challenge of high relative humidity levels in the environment or the subtle accumulation of moisture within the litter, maintaining control over this factor is a delicate balancing act. The consequences of neglecting moisture levels are profound and extend to the very core of layer health and productivity, demanding serious consideration.
The Unseen Consequences of Excessive Moisture
Elevated Ammonia Levels
When air moisture is not properly controlled, manure drying becomes inefficient, resulting in caked litter and elevated ammonia concentrations. This not only jeopardises layer health and performance but also poses health risks to humans over prolonged exposure.
Respiratory Distress
Elevated moisture levels create a breeding ground for harmful microorganisms such as bacteria, fungi and mould, which can release spores and toxins that induce respiratory problems in layers. This can manifest as irritated airways, laboured breathing, and diminished lung function, directly impacting growth rates and overall performance.
Heat Stress
Excessive relative humidity hampers hens’ ability to regulate body temperature efficiently, elevating the risk of heat stress. This common issue in layer houses can result in reduced feed intake, weight gain, and, in severe cases, mortality.
Health Issues
Damp litter and persistent moisture contribute to footpad dermatitis and breast blisters, causing painful lesions and increased vulnerability to infections. Beyond discomfort, this condition impairs mobility and overall health.
Decreased Feed Conversion
Birds stressed by excessive moisture redirect energy from growth to coping mechanisms, leading to decreased feed conversion rates. This not only impacts production costs but also indicates a compromised flock.
However, these issues do not crop up overnight. Problems related to moisture levels require time to show their symptoms, often over a few days or weeks. This means constant monitoring of house conditions is imperative – even when the situation seems under control – to ensure that moisture issues can be remedied before they become difficult to reverse.
The 3 Elements of Balancing Moisture Issues for a Thriving Flock
Keep Relative Humidity In Check with Efficient Ventilation
Effective ventilation is paramount to moisture control. Maintaining a target relative humidity of 40% to 60% is ideal to keep manure and litter dry. But this is not as simple as keeping the fans running 24/7, farm managers must make proper ventilation calculations based on house size, bird age, population and external climate. Then it’s about monitoring and tweaking ventilation levels, along with ensuring the air intakes and fans are functioning optimally.
At Big Dutchman, we offer a host of equipment and systems to ensure layer houses are well ventilated at all times. From powerful yet energy efficient exhaust fans such as the AirMaster Evo to versatile fresh air Wall Inlets that provide uniform air circulation throughout the entire house. Moreover, the entire ventilation system can be automated using advanced sensors and technology such as our ViperTouch climate computer.
Prevent Leaks in the Drinking Lines
Regular inspection and maintenance of water systems are vital to prevent leaks contributing to excessive moisture, which can cause litter caking and excessive build-up of ammonia. A well-designed drinking system must be flexible and robust enough to cater to the needs of the growing layers.
With a range of drinking systems, Big Dutchman is able to equip houses with pressure stable, hygienic and adequate water for layers. Products such as our Water Connection Units and Nipple Drinkers are robust and durable, featuring leak and spillage protection. Further enhancements can be made using our Electronic Water Alarm that can monitor water levels and temperatures in drinker lines, alerting farms managers of any issues in real-time.
Ensure the House is Airtight
The efficiency of the ventilation system relies on a well-sealed house. Cracks or loose areas allowing unintended air entry disrupt air circulation and elevate humidity. A house structure that is badly sealed will also cause the exhaust fans to work harder, hence increasing power consumption and overall costs.
One way to ensure layer houses are insulated and sealed to industry standards is opting for Big Dutchman’s Pre-engineered Buildings. These prefabricated modular building structures are designed for durability and promises outstanding air tightness, working in tandem with our products and equipment for optimal house conditions.
Maintaining proper moisture levels requires a careful balance of ventilation, water management and building the right structure. Big Dutchman’s solutions and expertise in layer production ensure egg producers can maintain an environment that promotes optimal conditions for both their workforce and their layers. Managing moisture effectively becomes a factor in cultivating a healthy and high performing flock.

Layer Moisture Control FAQs
- Why is water management important in layer houses?
Excessive moisture in the house can be disruptive to layer production. Issues such as diseases, health conditions, heat stress and poor feed conversion are common results of subpar moisture management - How does Big Dutchman’s ventilation solutions help with moisture control?
Big Dutchman can build a climate system that includes fresh air supply, ventilation fans, heating systems and computerised control units to keep humidity levels optimised. - How does air tightness affect moisture levels?
Proper air tightness is key to ensure ventilation fans perform as intended to remove excess moisture in the air. - How does high moisture cause heat stress in birds?
Excessive moisture results in higher humidity, which makes it difficult for birds to regulate their body temperature. This can cause reduced feed intake, decreased weight gain, and even mortality. - Why is dry litter important?
Litter consists of organic material and manure that the birds walk and rest on. If the litter is wet, this can cause diseases to spread easily, as well as cause conditions such as footpad dermatitis and breast blisters.
