PROBLEM TO BE SOLVED: To prevent sunlight from intruding into a hen house directly and indirectly. SOLUTION: An exhaust vent 24 connecting an indoor side to an outdoor side is formed at the upper portion of the wall surface of a hen house 1 where the pressure of inside 5 is increased by air that is blown into a room from an air supply opening 41 that is formed on a ceiling surface 4. At the upper portion of the outdoor side of the wall surface, a bottom surface part 54 and a side surface part 55, an upper surface part 56 that is extended from the upper end of the side surface part 55 to the bottom surface part side while being folded, and a light-shielding frame body 51 that has a screen piece 57 being suspended down from the tip of the upper surface part 56 and covers the outdoor side of the exhaust vent are provided. The upper end part of the side surface part 55 of the light-shielding frame body 51 is extended upward from the exhaust vent and upward from a roof front part 34 of the hen house, and the tip of the upper surface part 56 is extended from the tip part of the roof front part 34 to the upper position of a building side, thus allowing an exhaust opening 58 that is formed between the lower end of the screen piece 57 and the upper surface of the front part 34 to perform exhaust with an amount that is equal to or more than the amount of air being blown into the room from the exhaust vent 24.
