This run extension is designed to provide additional space for poultry and small animals and is compatible with Aivituvin chicken coops AIR27, AIR31, and AIR32, or can be used as a standalone enclosure.
Safety Information
- Read all instructions carefully before assembly and use.
- Adult assembly is required. Keep children and pets away during assembly.
- Inspect all components for damage before assembly. Do not use if any parts are damaged.
- Ensure the assembled run is placed on a stable, level surface.
- Regularly check the enclosure for any signs of wear, damage, or loose components to ensure the safety of your animals.
2. Setup and Assembly
Follow the included step-by-step assembly instructions carefully. It is recommended to have at least two people for assembly. A power drill can expedite the process, but use a low torque setting to prevent wood splitting.
Key Assembly Points:
- Component Identification: Lay out all parts and hardware. Refer to the parts list in your separate assembly guide to identify each component.
- Frame Construction: The run features an all-iron frame designed for durability. Ensure all frame connections are secure.
- Door Installation: Install the detachable front and rear doors, and the removable small left door as per the instructions. These doors are designed for easy access and combination with other coops.
- Perches: Install the two raised perches inside the run. These are designed for roosting and resting.
- Compatibility: If combining with an Aivituvin coop (AIR27, AIR31, AIR32), ensure the dimensions align correctly. The run's left door is 19.3"L x 14.4"H, and the front door is 26"L x 24.6"H. Measure your existing coop's access points before integration.

- Inspection: Periodically check the metal frame, wire mesh, and door latches for any signs of rust, damage, or loose connections. Tighten any loose screws.

- Perch Condition: Ensure perches are clean and securely attached.
5. Troubleshooting
This section addresses common issues you might encounter with your chicken run extension.
- Difficulty during assembly: Ensure all parts are correctly oriented according to the assembly guide. Do not overtighten screws, especially if using a power drill, to prevent material damage.
- Run feels unstable: Verify that all screws and connections are securely tightened. Ensure the run is placed on a flat, level surface.
- Predator concerns: The run provides a basic level of enclosure. For areas with active predators, additional predator-proofing measures (e.g., burying wire mesh, adding stronger latches, securing the top) may be necessary.
- Wire mesh detachment: If any wire mesh becomes detached, re-secure it using appropriate fasteners or wire ties.
- Cleaning challenges: For areas where bedding or debris accumulates, use a small brush or scraper to dislodge material. Regular, frequent cleaning can prevent buildup.
