When venturing into cage-free hen production, selecting the right aviary system is crucial. Here are some essential considerations and tips for optimizing your aviary setup.
Infrastructure Compatibility
One of the first factors to consider when choosing an aviary system is whether it will be installed in an existing building or a new construction. The system must fit the specific dimensions of the space. For instance, you need to ensure there is enough space between the top of the system and the ceiling—ideally 24 to 36 inches—to allow for proper ventilation and airflow.
This space consideration can help determine whether a two-tier or three-tier system is more appropriate. A two-tier system is easier to inspect and maintain, making it suitable for buildings with lower ceilings. In contrast, a three-tier system can increase bird density and is often chosen for new constructions to reduce the overall cost per bird.
Aisle Width and Layout
The width of the aisles in an aviary system significantly impacts the environment for the birds. It’s recommended to have aisles that are at least six to eight feet wide. This width allows birds to move around comfortably and prevents them from crashing into the equipment.
Wider aisles also improve visibility for inspections and enhance airflow, helping to keep the litter dry. This can contribute to a healthier environment for the birds and reduce maintenance tasks for the producer.
System Egg Collection
Efficient egg collection is vital in any aviary system. If system eggs are not collected promptly, it can encourage hens to lay more eggs in that area. This can be challenging if you are also managing floor eggs, feed systems, and morning egg collections simultaneously.
To address this, consider systems that facilitate prompt egg collection. Additionally, ensure that the area under the system is well-lit to prevent hens from laying floor eggs in the shadows. Some systems include features like a litter reduction mechanism in the morning to discourage hens from laying eggs underneath the system.
Optimizing Egg Quality
The quality of eggs produced is a critical factor when selecting an aviary system. The goal is to maximize the number of eggs laid in the nest. Key features that contribute to nest acceptance and egg quality include:
– **Nest Design:**
Nests should have curtains, an astro-turf style mat, and be isolated from the movement of hens and bright lights. This setup encourages hens to use the nest.
– **Single-Level Nesting:**
Having all nests on one level can improve egg quality by ensuring that all hens have sufficient space to lay eggs and that there is enough room on the egg belt.
By focusing on these features, producers can enhance egg quality and reduce the occurrence of floor eggs.
Conclusion
Choosing the right aviary system involves considering several factors, from infrastructure compatibility and aisle width to egg collection efficiency and egg quality optimization. By paying attention to these aspects, producers can create a conducive environment for their hens and improve overall production outcomes.
