The air inside the poultry house is fresh and well-circulated, which helps chickens thrive and grow healthily. Chickens have a higher body temperature than mammals, and they require more oxygen due to their increased respiratory rate—more than twice that of a mammal. Therefore, proper ventilation is essential to ensure a continuous supply of fresh air, keeping the chickens active and strong. It's recommended to ventilate the house every 2 to 3 hours for 20 to 30 minutes each time. Before opening the vents, it's important to raise the temperature slightly to avoid sudden drops that might stress the birds. Also, make sure the airflow doesn't directly hit the chickens, as this can cause discomfort and increase the risk of illness.
When chicken density is too high, it leads to poor air quality, with reduced oxygen levels and elevated carbon dioxide. This is especially problematic in hot and humid conditions, where a lack of fresh air can weaken chicks, making them more prone to disease and increasing mortality rates. To prevent this, it's advised to keep the stocking density at around 9 chickens weighing about 1.5 kg per square meter. If using an elevated wire floor system, the density can be slightly increased without compromising air quality.
During winter, when temperatures drop, maintaining warmth in a closed poultry house can lead to poor ventilation and oxygen deficiency. It's crucial to balance heating and ventilation properly to avoid negative effects on the chickens’ health.
Chickens are sensitive to stress, and any sudden changes—such as new sounds, unfamiliar colors, or unexpected movements—can cause them to become agitated, scream, and even fight. This stress increases their energy consumption and oxygen demand, which can negatively affect their growth and weight gain. To minimize stress, it's important to maintain a consistent and calm environment, ensuring the flock remains quiet and stable. A peaceful setting not only promotes better health but also reduces losses caused by unnecessary stress.
