Planning a poultry farm starts with one critical question: how many chickens can you house in a 4-tier battery cage? The answer depends on the number of doors per unit and the cell size. This guide gives you exact figures based on real product specifications so you can calculate your farm layout before purchasing.

The table below shows the exact capacity and dimensions for each cage configuration:

Understanding the 4-Tier Configurations

4 Tiers 4 Doors — 128 Birds per Set

This is the most popular choice for medium-scale farms. Each set measures 1.88m × 2.3m × 1.9m and houses exactly 128 birds — 4 birds per cell across 4 tiers and 4 doors. The 47cm × 35cm × 37cm cell size provides comfortable space per hen, supporting stable egg production.

Best for: farms of 1,000–3,000 birds Sets needed for 1,000 birds: approximately 8 sets Sets needed for 3,000 birds: approximately 24 sets

4 Tiers 5 Doors — 120 to 160 Birds per Set

With a narrower cell (39cm × 35cm × 37cm), this configuration fits more doors in the same house width. Capacity ranges from 120 to 160 birds per set depending on your stocking density. The smaller cell size is suitable for lightweight layer breeds such as Hy-Line and Lohmann Brown.

Best for: farms of 2,000–5,000 birds Sets needed for 2,000 birds: approximately 13–17 sets Sets needed for 5,000 birds: approximately 32–42 sets

4 Tiers 5 Doors — 160 to 200 Birds per Set (Large Cell)

This configuration uses a larger cell size of 43cm × 45cm × 41cm and houses 5 birds per cell. The overall set dimensions are 2.15m × 2.3m × 2.1m, making it the highest-capacity A-Type option available. It suits larger layer breeds and farmers who want to maximize production per set.

Best for: farms of 5,000–10,000 birds Sets needed for 5,000 birds: approximately 25–32 sets Sets needed for 10,000 birds: approximately 50–63 sets

How to Calculate How Many Sets You Need

Use this simple formula:

Sets needed = Total birds ÷ Birds per set

Example 1: You want to keep 1,000 birds using 4-tier 4-door cages (128 birds per set): 1,000 ÷ 128 = 8 sets (round up to 8–9 sets)

Example 2: You want to keep 5,000 birds using 4-tier 5-door large cell cages (160–200 birds per set): 5,000 ÷ 180 = 28 sets (use midpoint capacity)

Poultry House Size Planning

Once you know how many sets you need, plan your house dimensions:

• Allow 1.2–1.5m working aisle between cage rows and along walls
• Standard house layout: 2 rows of cages running the length of the house
• House width: 8–10m comfortably fits 2 rows of A-Type cages with aisles
• House length: number of sets per row × set width + 1.5m end space

Example layout for 1,000 birds (8 sets of 4-tier 4-door):

• 4 sets per row × 1.88m = 7.52m per row
• House length: approximately 9–10m
• House width: 8m (2 rows + aisles)
