What is the impact of humidity levels on chicks aged 7-21 days during rearing?

  1. Promotes growth

  2. Affects respiratory health

  3. Maintains feather quality

  4. Enhances feed efficiency

The correct answer is: Affects respiratory health

Humidity levels play a critical role in the respiratory health of chicks aged 7-21 days during rearing. At this age, chicks are particularly vulnerable to respiratory issues, and maintaining appropriate humidity levels is essential for their overall well-being. High humidity can lead to the proliferation of pathogens in the environment, which can compromise respiratory function. Conversely, low humidity can cause dehydration and stress, further impacting respiratory health. Proper humidity levels support optimal ventilation and help ensure that chicks can efficiently exchange gases, which is vital for their growth and development. Thus, monitoring and controlling humidity is crucial for preventing respiratory diseases and promoting effective health management in young chicks. Other factors, while important to poultry management, are not as directly influenced by humidity as respiratory health is at this critical growth stage.
