Brooders are specialized devices or structures used to provide warmth and shelter for young animals, particularly chickens and ducklings. They create a controlled environment that mimics the warmth of a mother bird, ensuring that the chicks stay warm and safe during their early development. These systems can be electric or heated by other means, and they often include features like adjustable temperature settings and ventilation. Proper use of a brooder is essential for the health and growth of the young animals, as it helps prevent issues like hypothermia and promotes better feeding and growth rates.
