How much temperature is suitable for duck breeding

The growth of ducks must be suitable temperature, to avoid the room temperature rise and fall dramatically. 1-3 days of age, the temperature is 28-30C?; 4-6 days of age, the temperature is 24-26C?; 7-10 days of age, the temperature is 20-23C?; 11 days after the analogous. In the first period, when the room temperature is lower than 20C?, infrared lamps or electric heating panels can be used for heating. Pay attention to prevent ducks from piling up and evacuate them in time.
