Free run (animal)

Free run, in the context of animal husbandry, refers to a system of housing and management where animals, typically poultry (such as chickens) or pigs, are allowed to move relatively freely within a defined indoor space. This contrasts with more restrictive systems like battery cages or gestation crates.

Free run systems typically provide:

• Freedom of Movement: Animals can move within the confines of the barn or building, allowing for natural behaviors like walking, wing-flapping (in poultry), or exploring.

• Social Interaction: Animals have the opportunity to interact with each other, forming social hierarchies and engaging in group activities.

• Access to Resources: Feed and water are typically distributed throughout the free run area, ensuring access for all animals. Nesting areas (for laying hens) or designated resting spaces are also usually provided.

However, free run systems also present specific challenges:

• Increased Risk of Disease: Higher animal densities can lead to a greater risk of disease transmission.

• Potential for Aggression: Close proximity can sometimes lead to increased aggression and pecking orders within the animal population.

• Management Complexity: Managing a free run system requires skilled labor and careful attention to environmental factors like temperature, humidity, and ventilation to maintain animal welfare.

The term "free run" is often used in marketing and labeling of animal products, particularly eggs and meat. It is important to note that "free run" does not necessarily equate to "free range." Free range systems provide animals with access to outdoor areas, whereas free run systems are entirely indoors. Consumer understanding of these terms is often limited, and standards for their use can vary by region and jurisdiction.
