Poultry Feeding Systems — Pan, Auger, Chain: How to Choose
The feeding system determines feed conversion, uniformity and labour cost more than any other single asset in the house. This guide compares pan, auger and chain systems, and defines the spec items your quotations must include.
Overview
What it is
Silo-to-bird feed delivery: outdoor silos, flexible or rigid augers, chain or pan lines, weighing hoppers and controllers.
Typical applications
- Broilers, breeders and pullets on floor
- Turkey grow-out
- Layer houses (chain/pan in aviary; cage-integrated in colony)
Benefits
- Uniform feed access → better flock uniformity
- Automated portioning → labour reduction
- Feed-consumption data via weighers → early disease signal
Limitations & trade-offs
- —Wear items (pans, motors, gearboxes) drive OPEX
- —Auger vs chain choice locks in feed particle-size handling
- —Silo location affects moisture and mycotoxin risk
Typical project sizes
- Small: 1–2 lines, single silo
- Medium: 4–6 lines per house, dual silo
- Large: 6–10 lines with weighing and remote monitoring
Technology comparison
| Criterion | Pan feeding (broiler) | Chain feeding (breeders/layers) |
|---|---|---|
| Feed uniformity | Very good | Good with correct chain speed |
| Grain fines handling | Excellent | Sensitive to fines |
| Bird access positions | 12–14 birds/pan | Linear m per bird — precise |
| CAPEX / m | Higher | Lower |
| Maintenance intensity | Pans, drop tubes, corner units | Chain, motor, corners, tension |
| Best fit | Broilers, heavy turkeys | Breeders, floor layers, aviary |
Buying guide
- Match auger diameter to feed pellet size and daily throughput.
- Choose gearmotors from tier-1 suppliers (SEW/Bonfiglioli/Nord equivalent) and confirm ingress rating (IP55+).
- Specify pan drop tubes for the age range you feed — restricted access for chicks, open for finishers.
- Ask for line-weighing option; it pays back within the first year on data alone.
- Confirm anti-perch design on lines used with turkeys and heavy broilers.
Technical specification checklist
- Bird species, target end-weight, and cycle days
- Number of feed lines per house and pan spacing
- Auger diameter and length; motor kW
- Feed particle sizes (crumble, pellet, mash) and expected fines %
- Silo volume, material, and moisture-management features
- Feed-line weighing (yes/no) and integration with controller
- Winch system for line height adjustment
Budget guide
Class 4 indicative ranges only — actual quotations depend on brand tier, options, freight and site conditions. Use as a sanity check on incoming offers.
| Scale | Indicative CAPEX | Main cost drivers |
|---|---|---|
| Small | USD 12–25k / house | 2 lines, 1 silo, basic controller |
| Medium | USD 25–55k / house | 4–6 lines, dual silo, winches |
| Large | USD 55–110k / house | 6–10 lines with weighing, remote monitoring |
Procurement checklist — before you RFQ
- Define production goals (birds/cycle, cycles/year, target FCR/egg mass)
- Confirm utilities available on site (power kVA, water m³/day, gas, roads)
- Define project scope: new build, upgrade, or expansion
- Prepare preliminary site layout and building dimensions
- Confirm local regulations, environmental permits, and biosecurity zoning
- Determine financing path (self-funded, ECA-backed, leasing, blended)
- Create technical specification (this page's spec checklist)
- Prepare RFQ package with drawings, spec, Incoterms and payment terms

Frequently asked questions
Pan or chain for a floor layer house?Open
Chain is the traditional and often more economical choice for floor layers and breeders; pan systems win when uniform access for heavier birds is the priority.
How many silos do I need?Open
Two silos per house is the professional minimum — one is always ready to receive delivery while the other feeds birds, and it lets you switch feed phases without downtime.
