The biggest difference between a closed house and an open house is that a closed house relies entirely on mechanical ventilation and artificial temperature control. Closed house has strong insulation capacity, but once the ventilation system fails, the air quality inside the house will deteriorate rapidly within tens of minutes. Therefore, at this time of year, the core of a closed-layer chick brooding house is not "burning more heat," but "getting minimum ventilation right." The cross-sectional diagram below shows the correct airflow organization logic for winter.
As shown in the figure, the correct airflow path is: cold air enters through the side windows on both sides → is directed in along the ridge direction → mixes and preheats in the hot air zone at the top → warm air flows evenly downward through the H-type equipment → exhaust air is extracted by fans. The key is that cold air must not "drop onto the chickens as soon as it enters the windows." For the current season, the following points should be strictly controlled in a closed-layer chick brooding house:
Key point: For winter brooding in a closed house, "ventilation is a necessity, insulation is the goal"—first ensure the minimum ventilation rate and correct airflow direction, then use heating to make up the temperature, rather than conversely relying on "stuffiness" to keep warm.
