For intensive farming with hens kept on the floor, the smallest unit when building from newis based on a shed width of 7m; if battery coops are used, the shed width is 6-15m . The shed must be thermally insulated, the optimum shed temperature according to the application,
being between 15 and 22°C.

Cellars for droppings below the battery coops needs a longitudinal air extraction system under the service aisles.
Ventilation system needs to have the following capacity :
- Air entry speed: 0.30 m/s (maximum 0.50 m/s )
- In summer, air circulation for laying hens reaches a maximum of 10 m3 /h/kg bird;
- For young hens and broilers, it is 4.00 m3/h/kg bird.
An automated round drinking trough unit is sufficient for 75-100 hens; with channel trough,allow 1.00 m for 80-100 hens. A tubular feeding unit is adequate for 25 hens per round trough (diameter 30 cm)
