Sudden death in laying hens is a major concern during the summer months due to the extreme environmental conditions. High temperatures, humidity, and poor ventilation can create a stressful environment for chickens, especially those that are already under pressure from high egg production. This condition is often referred to as "egg fatigue" or "summer disease," and it has become increasingly common in recent years. It typically affects newly introduced hens or those in their peak production phase, making them more vulnerable during hot weather.

Some of the key signs include sudden deaths at night, with dead hens found in the morning when feeding. Affected birds often have a prominent cloaca and tend to be overweight. Additionally, some hens may appear lethargic or show signs of pheasant-like behavior. If detected early, removing these affected hens can prevent further losses. The condition tends to spread quickly, especially when there's a sudden temperature rise, and it often affects multiple farms in the same area.

The causes of this syndrome are mainly related to environmental stressors. High temperatures combined with poor ventilation lead to heat stress, which increases respiratory rates and causes acid-base imbalances in the body, potentially leading to respiratory alkalosis. Inadequate cooling systems, overcrowding, and improper feeding practices also contribute significantly. For example, feeding hens 3-4 times a day during the hottest hours can increase their metabolic burden, leading to heart failure and death.

To prevent sudden death, proper management is essential. Ensuring good ventilation, maintaining optimal stocking density, and providing adequate cooling are crucial steps. Using eco-friendly solutions like the Golden Fish Fermentation Bed can greatly reduce the risk. These beds improve the overall living environment by reducing stress, promoting better air quality, and supporting gut health through beneficial bacteria. As a result, hens become more resilient and less prone to sudden illness, leading to healthier flocks and better productivity.

By taking proactive measures and focusing on environmental control, poultry farmers can effectively manage the risks associated with sudden death in laying hens during the summer. This not only improves animal welfare but also enhances the economic sustainability of the farm.
