Chain feeding systems: specification, sizing and supplier comparison.

A component-level reference for buyers specifying chain feed lines in breeder, pullet and floor-layer houses — chain speed, trough geometry, drive sizing, trough space per bird and the spares that decide long-term uptime. Free, vendor-neutral RFQ support if you want quotes on the specification.

What a chain feed line consists of

A closed steel trough circuit, a flat-link chain, corner wheels, a drive unit with gearbox, a feed hopper with level control, suspension and winch gear, and the controller that runs the feeding programme. Each of those is a separate line item in a quote — a bid that prices only 'feeding system, per house' cannot be compared against one that itemises drives, corners and hopper fill.

Specification bands to fix before the RFQ

Chain speed 12–36 m/min (18 m/min is the usual breeder setting); trough width 45–70 mm; chain thickness 4–6 mm hardened flat link; drive units 0.37–1.5 kW according to circuit length; and 100–150 m of circuit per drive as a working maximum. Fix these in writing so every manufacturer quotes the same machine, not their default catalogue build.

Trough space per bird

Broiler breeder females need roughly 15–18 cm of trough per bird, males 20–22 cm, floor layers 10–12 cm. Multiply bird count by the figure, halve it for double-sided access, and check the result against your house length before you accept any layout drawing. Under-specified trough space shows up as flock uniformity loss, not as an equipment fault.

Indicative cost bands

For planning only, not a quotation: USD 9–16 per running metre ex-works for trough, chain, corners and suspension; USD 1,200–3,500 per drive unit; USD 2,000–6,000 per hopper and fill system. Landed cost on CIF or DDP terms typically adds 15–30% for freight, packing and duty depending on origin and destination.

Selection criteria that matter after year one

Corner-wheel bearing quality and replacement cost, chain hardness and the supplier's replacement-section lead time, gearbox service access, level-sensor reliability, and whether the controller integrates with your existing climate computer. Ask for a priced two-year spares package with each offer — the gap between bidders is often larger there than on the headline price.

Retrofit into an existing house

Scope retrofits against truss spacing and suspension points, floor-level tolerance along the trough run, spare electrical capacity for the drives, and the turnaround window between flocks. A simple level survey along the intended line is the most valuable document you can attach to the RFQ.

How to get comparable quotes

One written scope, one Incoterms basis, the same spares package and the same commissioning requirement to every bidder. HatchMatch issues that RFQ across vetted manufacturers, normalises the offers on a single comparison sheet, and charges the buyer nothing.

FAQ

Common questions

What is a chain feeding system in poultry?

A chain feeder circulates a flat steel chain through a closed feed trough around the house, drawing feed from a hopper and distributing it evenly along the whole line. It is the standard choice for breeder and layer flocks where controlled portions, fast distribution and uniform access matter more than the pan-per-bird geometry used in broiler grow-out.

Chain feeder or pan feeder — which should I specify?

Chain feeders suit breeders, pullets and floor-layer houses: distribution in 3–6 minutes limits competition during restricted feeding, and trough space per bird is easy to audit. Pan feeders suit broiler grow-out, where ad-lib access, lower feed spillage and easier chick start-up dominate. Mixed houses often run male chain lines with female pan lines.

What are typical chain feeding system specifications?

Chain speed 12–36 m/min (18 m/min is the common breeder setting), trough width 45–70 mm, chain thickness 4–6 mm hardened flat link, corner wheels with sealed bearings, drive units of 0.37–1.5 kW depending on total circuit length, and hopper capacity sized to one full distribution. Line lengths of 100–150 m per drive are common; longer circuits need a second drive or a heavier chain.

How much do chain feeding systems cost?

As an indicative planning band only — not a quote — a complete chain feed line typically runs USD 9–16 per running metre ex-works for the trough, chain, corners and suspension, plus USD 1,200–3,500 per drive unit and USD 2,000–6,000 per hopper and fill system. Landed cost on CIF or DDP terms usually adds 15–30% depending on origin, duty and freight.

How do I size trough space per bird?

Work from trough length available on both sides. Broiler breeder females typically need 15–18 cm of trough per bird, males 20–22 cm, and floor layers 10–12 cm. Multiply bird count by that figure, divide by two for double-sided access, and that is the circuit length your house layout must accommodate.

What fails first on a chain feeder, and what spares should I stock?

Corner wheels and their bearings, the chain itself at the corners, drive-unit gearboxes and the hopper level sensor. Ask every bidder to quote a two-year spares package with corner wheels, a spare chain section, one gearbox and level sensors, and confirm lead time for each item before signing.

Can I retrofit chain feeding into an existing house?

Usually yes. Retrofits are scoped against existing truss spacing and suspension points, floor level tolerance along the trough run, available electrical capacity for the drives, and the turnaround window between flocks. A level survey along the intended trough line is the single most useful thing to have before an RFQ.

How do I get comparable chain feeder quotes?

Issue one written scope — bird numbers, house dimensions, required trough space per bird, chain speed, feeding programme, and a single Incoterms basis — to every bidder. HatchMatch runs that RFQ on your behalf, at no cost to the buyer, and returns the offers on one comparison sheet within 2 business days of a complete brief.
