Unit size is 4.8 m x 9.4 m . Insulation is optimal and has a single sloped roof with its main facade facing south.

  Ventilation is natural. Artificial lighting is controlled by a timer, which can be programmed to any required photoperiod, to an intensity of 5 lux.

  The unit is equipped with an stair-step battery in 3 levels, with 9 cages on each side and each level, in total 54 cages. Up to 6 birds can be placed in each cage (580 cm2/bird), thus allowing a total number of 324.

  Each row and side of the battery has an independent drinking water tank (that is, 6 tanks in total). Each cage holds 2 cup drinkers and one feeder outside the cage. Droppings are collected in the pit on the floor.

  Broilers are marketed at 40-45 days, thus allowing 6 crops a year. The placing of day-old chicks and the marketing of the broilers are coincident with the same operations in a nearby house for broilers on the floor, for obvious sanitary reasons.
