1. Introduction to Cage Free Housing System

The Cage Free Housing System represents a modern and ethical approach to poultry farming, focusing on the welfare and natural behaviors of laying hens and broilers. Unlike conventional caged systems where birds are confined in small wire cages, cage free systems provide birds with unrestricted movement inside a barn or aviary, allowing them to walk, perch, nest, and forage.

Driven by consumer demand for ethically produced eggs and poultry, as well as stricter animal welfare regulations worldwide, cage free housing systems have become an increasingly popular choice for farmers aiming to balance productivity with sustainability and animal welfare.

This system incorporates advanced housing equipment designed to maximize comfort, health, and productivity of the flock while optimizing farm management efficiency.

2. Technical Parameters of Cage Free Housing System

Cage free housing systems vary by design and scale, but the key technical parameters to consider include:

2.1 Housing Structure

• Building Size: Typically ranges from 500 m² to over 10,000 m² depending on flock size

• Floor Area per Bird: Recommended 750 cm² to 1,000 cm² per bird as per welfare standards

• Height: Minimum 2.5 to 3 meters to allow adequate air circulation and movement

2.2 Equipment Included

• Nest Boxes: Manual or automated nests, typically 1 nest per 4–5 hens

• Perches and Racks: 15–20 cm perch length per bird to satisfy roosting behavior

• Feeders: Linear or pan feeders to provide 12–15 cm feeding space per bird

• Drinkers: Nipple or bell drinkers, with 1 nipple per 10 birds as a general guideline

• Lighting: LED lighting systems with dimming and timers for optimal day length control

• Ventilation: Tunnel or natural ventilation systems maintaining 15–20 air changes per hour

• Manure Management: Slatted floors with manure belts or scrapers for waste removal

• Environmental Controls: Temperature and humidity sensors, automated fans, and curtains

2.3 Flock Size

• Suitable for flocks from 5,000 to 100,000+ birds depending on facility size and management

2.4 Biosecurity Features

• Entry airlocks, footbaths, insect screens, and controlled access points

3. Key Features of Cage Free Housing System

3.1 Animal Welfare Focus

Designed to allow natural behaviors including walking, dust bathing, wing flapping, perching, and nesting.

3.2 Spacious Environment

More space per bird compared to conventional cages, reducing stress and aggression.

3.3 Advanced Environmental Control

Integrated climate control systems maintain optimal temperature, humidity, and air quality.

3.4 Automated Feeding and Drinking

Efficient feed and water delivery systems ensure consistent nutrition and hydration.

3.5 Manure Removal Systems

Automated belts or scrapers maintain cleanliness and reduce ammonia levels.

3.6 Lighting Management

Programmable LED lighting promotes healthy laying cycles and reduces cannibalism.

3.7 Easy Monitoring

Centralized control panels and sensors enable real-time monitoring of environmental conditions and bird behavior.

4. Advantages of Cage Free Housing System

4.1 Improved Animal Welfare

Promotes natural behaviors and reduces health issues linked with confinement, such as osteoporosis and foot lesions.

4.2 Higher Market Value

Eggs and meat from cage free systems typically command premium prices in retail markets.

4.3 Consumer Trust and Brand Image

Aligns with increasing consumer demand for ethically produced animal products.

4.4 Better Air Quality

Improved ventilation reduces respiratory diseases and enhances bird comfort.

4.5 Enhanced Production

Although sometimes lower than conventional cages, many farms report stable or improved egg quality and bird health.

4.6 Reduced Mortality

Lower stress and better mobility contribute to reduced mortality rates.

5. Application Scenarios

5.1 Commercial Layer Farms

For egg production operations transitioning from caged systems to cage free.

5.2 Broiler Farms

Used to improve welfare and meat quality by allowing natural behaviors.

5.3 Organic and Free-Range Farms

Often combined with outdoor access for premium organic products.

5.4 Research and Educational Farms

For studying poultry behavior and welfare improvements.

5.5 Small and Medium Scale Farms

Modular systems designed for flexible flock sizes.

6. Installation and Usage Instructions

6.1 Site Preparation

• Ensure site is well-drained and accessible

• Prepare building foundation and utilities (electricity, water, ventilation)

6.2 Equipment Setup

• Assemble nests, perches, feeders, and drinkers as per manufacturer guidelines

• Install manure belts or scrapers under slatted floors

• Set up lighting and ventilation control panels

6.3 Stocking Birds

• Follow recommended stocking densities

• Introduce birds gradually to reduce stress

• Monitor flock closely during initial days

6.4 Daily Management

• Check feed and water supply regularly

• Monitor environmental conditions (temperature, humidity)

• Inspect birds for health issues and abnormal behavior

• Remove manure regularly to maintain hygiene

6.5 Routine Cleaning

• Clean feeders and drinkers weekly

• Deep clean housing between flocks to prevent disease

7. Maintenance Guidelines

• Regularly inspect and repair mechanical systems (feeders, drinkers, manure belts)

• Replace damaged perches or nests promptly

• Maintain ventilation filters and fans

• Update control software as needed for automation systems

8. Troubleshooting Common Issues

Issue 1: Increased Aggression Among Birds

• Cause: Overcrowding or poor environmental conditions

• Solution: Reduce stocking density, optimize lighting and ventilation

Issue 2: Poor Egg Production

• Cause: Suboptimal nutrition or stress

• Solution: Adjust feed formulation, improve environmental control

Issue 3: Manure Accumulation

• Cause: Manure belt malfunction or improper cleaning schedule

• Solution: Repair or replace belts, adhere to cleaning protocols

Issue 4: Respiratory Problems

• Cause: Poor ventilation or high ammonia levels

• Solution: Improve airflow, increase fresh air exchange

9. Frequently Asked Questions (FAQ)

Q1: What distinguishes cage free from free-range systems?

Cage free means birds have indoor freedom of movement, while free-range includes outdoor access.

Q2: Can cage free systems accommodate large flocks?

Yes, systems are scalable to tens of thousands of birds.

Q3: How much space does each bird need?

Minimum 750 cm² to 1,000 cm² per bird is recommended for welfare.

Q4: Are cage free eggs more expensive?

Typically yes, due to higher production costs and consumer demand.

Q5: How do I control temperature in a cage free house?

Using automated ventilation, fans, and heating systems controlled via sensors.

Q6: How often should manure be removed?

Daily or multiple times per day with automated manure belts for hygiene.

Q7: Can cage free systems reduce disease risks?

Better air quality and lower stress can reduce some diseases but biosecurity is still essential.

Q8: What is the lifespan of cage free equipment?

Typically 10-15 years with proper maintenance.

10. Conclusion
