What to consider when choosing the egg production system?

These are the main factors to consider when choosing the system of egg production.

The density

The density is defined as the maximum number of hens in the floor area. The legislation sets the following limits:

Floor, on one level: 7-8 hens per square meter
Aviary, on several levels: 12-35 chickens per square meter
enriched Batteries: 40-60 chickens per square meter


Feed intake should be higher in production on the ground and aviary, because birds can move easily and perform more exercise than birds in cages.


The labor required will be greater in production on the ground and aviaries production on battery cages. For example, UTH (Unit Human Work), which measures the number of birds that can carry a person, would be between 60,000 to 80,000 in battery cages while in production on the ground and aviaries could not exceed 40,000.

Investment per hen

The investment per hen will always be higher in the case of production on the floor or aviary (about 25-35 € per bird) lie in battery production can lower costs (€ 21-28 per bird) .

Rating egg “camper”

We must take into account the growing awareness for animal welfare among consumers. In this sense, the production systems on the ground and allow aviary birds have access to an outside, bringing their eggs camperos acquire qualification. However, this does not happen with the production of eggs in battery cages.
