When designing a poultry house, it is important to pay close attention to the roof and walls. The roof should be designed to provide adequate ventilation while still protecting the birds from the elements.

Additionally, the walls should be spaced appropriately to ensure optimal airflow and temperature control. Window grills are also important as they provide additional ventilation and allow natural light to enter the poultry house.

Proper design of the roof and walls, as well as the inclusion of window grills, can help ensure the health and safety of the birds and improve their overall productivity.
