Can an Existing Poultry House Be Converted from A-Type to H-Type Layer Cages?
Yes — often, but not as a simple cage-for-cage swap. The building must be rechecked for H-Type height, row layout, bird density, ventilation, utilities, manure and egg routes, service access and structural condition before the conversion is approved.

Direct Answer
An existing poultry house can often be converted from A-Type layer cages to an H-Type layer battery cage system, but the final answer depends on the building — not on the cage name.
The house must have enough clear height, usable width and length, structural condition, ventilation potential, electrical / water capacity and row-end service space for the selected H-Type configuration.
Before quoting a final layer battery cage system, the supplier should check whether the existing building can support the new poultry house layout, automatic feeding system, automatic egg collection system, manure removal system and climate control system.
Conversion Is Not the Same as Upgrading A-Type Automation
Before removing cages, separate two questions: Do you need more automation? and Do you actually need a different cage structure?
An A-Type house can also use an automatic feeding system, automatic drinking system, automatic egg collection system, manure removal system and climate control system.
If the existing A-Type layout still fits the farm’s capacity and labor plan, upgrading selected automation may be more economical than replacing the entire cage system. H-Type conversion makes more sense when the project needs higher bird density, more standardized automation, less repetitive labor, or a new expansion strategy.
The First Retrofit Decision: Keep, Replace or Redesign?
Building Infrastructure
- main house shell;
- roof and wall structure;
- parts of floor / drainage;
- water source;
- selected utility mains;
- farm roads and service areas.
Cage-Level Equipment
- A-Type cage rows;
- cage support structure;
- row feeding equipment;
- cage drinking layout;
- egg transfer equipment;
- manure equipment and row drives.
House Systems
- ventilation and cooling;
- feed distribution;
- egg / manure discharge;
- electrical control;
- water pressure;
- service aisles and access.
House Fit Test: 8 Conditions to Check Before Selecting H-Type Layer Cages
Width planning matters as much as total flock size
Even if the house is long enough, the usable width decides how many H-Type rows can be arranged while still keeping inspection aisles and row-end equipment space. Existing-house conversion should therefore be checked from the building envelope inward.

Before and After: What Actually Changes?
What Happens to the Existing A-Type Equipment?
| Existing Component | Possible Retrofit Treatment | Why |
|---|---|---|
| A-Type layer cages | Normally removed | Different cage geometry and support structure. |
| Main feed storage | May be reusable | Reuse only if capacity and interfaces match the new automatic feeding system. |
| Cage-level feeding | Usually redesigned | H-Type rows use a different feeding route. |
| Main water source | May be reusable | Capacity and water quality must be adequate. |
| Cage drinking lines | Redesigned | Nipple positions, regulators and tier routing change. |
| Egg collection | Usually replaced / redesigned | Row heights and transfer geometry differ. |
| Old scraper / manure pit | Must be reassessed | H-Type systems commonly use manure belts and a new manure removal system route. |
| Fans / cooling | Recalculate before reuse | Final bird density and cage obstruction change airflow demand. |
Three Possible Conversion Outcomes
GREEN — Retrofit Is Practical
Sufficient height and width, suitable building condition, utilities can support automation, and ventilation can be upgraded without major reconstruction.
AMBER — Retrofit with Modifications
Doors, floor, electrical supply, cooling, water pressure or equipment-end space require civil / utility changes. Compare the modification budget with a new-house option.
RED — New House May Be Better
Clear height is too low, columns block rows, the building needs major reconstruction, ventilation is difficult to upgrade, or the retrofit creates poor long-term efficiency.
Retrofit Existing House vs Build a New H-Type Poultry House
| Decision Factor | Retrofit Existing A-Type House | New H-Type House |
|---|---|---|
| Building shell | Reuse if suitable | New |
| Layout freedom | Limited by existing dimensions | High |
| Ventilation | Often needs modification | Designed around final density |
| Electrical / utilities | May need upgrade | Sized correctly from the start |
| Production disruption | Existing house must be emptied | Old house can potentially continue operating during construction |
| Expansion | Depends on old site layout | Easier to standardize |
| Hidden structural risk | Higher | Lower when properly designed |
| Long-term layout efficiency | Depends on existing building | Usually easier to optimize |
Already have the existing poultry-house dimensions?
Send internal length × width × clear height, column positions, photos and target layer capacity. The first step is to decide whether the house is worth converting before the layer cage quantity is quoted.
Conversion Workflow: From Existing A-Type House to H-Type Layout
Survey the Existing House
Measure internal dimensions, columns, doors, fans, cooling, service rooms and electrical panels. Take photos from both ends and along the side walls.
Confirm the Target Capacity
Decide whether the retrofit should keep the same flock size, increase capacity, reduce labor or standardize with future H-Type layer cage houses.
Select Candidate H-Type Configurations
Compare tier and cage options against the building survey rather than selecting the model from bird number alone.
Test Rows and Cage Quantity
Use rows × sets per row × birds per set to calculate installed capacity, then verify aisle and equipment-end space. See the related 30,000-layer H-Type cage quantity and house-size guide.
Recalculate Automatic Systems
Redesign the automatic feeding system, drinking system, automatic egg collection system, manure removal system, climate control system and poultry management system.
Identify Structural & Utility Upgrades
Confirm civil work, electrical capacity, water pressure, fan/cooling upgrades and service-end modifications.
Compare Retrofit vs New House
Include equipment, demolition, civil work, installation, downtime and long-term operating efficiency.
Freeze the Final Drawing Before Production
Row positions and equipment directions should be approved before manufacturing because changes can affect multiple automatic poultry equipment systems.

After the H-Type configuration, house modifications and final equipment layout are confirmed, installation support should follow the project and contract scope.
According to the project and contract scope, LIVI engineers can be arranged to provide on-site installation and commissioning guidance. For projects using remote installation support, LIVI can provide drawings, manuals, videos and online technical guidance.
FAQ: Converting an A-Type House to H-Type Layer Cages
Can an open-sided A-Type poultry house be converted to H-Type layer cages?
It may be possible. H-Type layer cages can be used in different poultry-house types, but final bird density, ventilation, climate and equipment layout must be checked for the specific building.
Is house height the most important measurement?
It is one of the first checks because H-Type systems stack vertically. Width, length, columns, ventilation, utilities and row-end space are equally important to the final design.
Can the old A-Type feeding system be reused?
Some main feed infrastructure may be reusable if capacity and interfaces are compatible. Cage-level feeding equipment normally requires redesign for H-Type rows.
Can the old manure scraper be used with H-Type cages?
Do not assume so. H-Type systems commonly use manure belts beneath the tiers, so the manure-removal route normally needs a new design.
Will conversion always increase bird capacity?
No. Capacity increases only when the selected H-Type system, usable house dimensions, service space and ventilation allow it.
Is conversion always cheaper than a new poultry house?
No. Major structural, ventilation, electrical and civil modifications can reduce the financial advantage of retrofit.
Should the A-Type cages be dismantled before the retrofit design?
No. Measure and evaluate the existing house first. Confirm the conversion concept before major demolition begins.
Final Answer
An existing A-Type poultry house can often be converted to H-Type layer cages — but it should be treated as a building retrofit, not a cage replacement.The conversion is most practical when the building already has adequate height + width + length + structural condition + ventilation potential + utilities + row-end service space.
Use this sequence: survey the house ? select H-Type configuration ? test rows and capacity ? redesign automatic poultry equipment and ventilation ? identify civil upgrades ? compare retrofit vs new house ? approve final layout.
