Calculation methodology

How every HatchMatch poultry calculator works

All 31 documented public calculators use disclosed calculation models (version 2.0.0, reviewed 2026-08-21), so a formula corrected in one tool is corrected in every tool. This page publishes each model's inputs, units, formula, biological assumptions, welfare limits, engineering assumptions, limitations and the professional who must confirm the result.

Machine-readable version: /api/public/calculator-methodology.json

Planning estimate only

Planning estimate only. Final bird density, biological assumptions, house design, ventilation, equipment selection, welfare compliance, price and performance must be confirmed by qualified independent professionals, the selected provider and applicable authorities.

No calculator on this site replaces poultry-production planning, veterinary advice, breed or strain management guidance, welfare and stocking-density requirements, detailed ventilation and climate engineering, structural engineering, electrical and fire design, biosecurity planning, local permits, supplier design or lender due diligence.

HatchMatch Group does not guarantee mortality, feed conversion ratio, growth rate, market weight, cycles per year, egg production, hatchability, fertility, chick quality, revenue, profitability.

Documented calculation models

Bird capacity and stocking density

v2.0.0 · confidence: medium · reviewed 2026-08-21

Convert a live-weight stocking limit and a target market weight into an indicative bird capacity for a house of known floor area.

Poultry types: broiler, layer (floor system) · Life stages: grow-out to target weight · Housing: floor / deep litter · Climate: climate-independent; the applicable limit may be lower where ventilation cannot sustain it

Inputs and units

Gross house floor aream²buyer-input
Target live weight at depletionkgbuyer-input
Live-weight stocking limitkg/m²regulatory-limit

How it is calculated

  • usable area = gross floor area × (1 − 4% service and equipment space)
  • birds per m² = applied live-weight cap ÷ target live weight
  • indicative capacity = usable area × birds per m²
  • conservative scenario applies a 3 kg/m² margin below the entered limit; no scenario ever exceeds it

Planning outputs

  • planning cap applied (kg/m²)
  • usable production area (m²)
  • birds per m² at target weight
  • indicative capacity range (birds)
  • slaughter live-weight output (t)

Biological assumptions

  • Target live weight is a buyer input, not a strain guarantee.
  • Capacity is at depletion; the placement count must additionally allow for expected mortality.

Welfare and regulatory assumptions

  • The kg/m² limit is entered by the buyer and treated as a hard ceiling.
  • Limits differ by jurisdiction, housing system, ventilation capability and export-market scheme.

Engineering assumptions

  • 4% of gross floor area is reserved for service room, control room and equipment ends.

What this tool cannot do

  • Not valid for enriched cage, colony or aviary systems, which are sized on usable tier area, perch length and nest provision rather than floor area.
  • Does not evaluate whether the ventilation system can actually sustain the density on a design day.
  • Does not present any universal birds/m² recommendation.

What must be confirmed

  • the competent welfare and permitting authority
  • the selected equipment supplier or integrator
  • a poultry veterinarian or production specialist

Poultry house sizing

v2.0.0 · confidence: medium · reviewed 2026-08-21

Derive indicative house dimensions and a first-pass tunnel fan count from a bird count and a density assumption.

Poultry types: broiler, layer (floor system), breeder · Life stages: grow-out, production · Housing: floor / deep litter · Climate: climate-independent for area; fan count assumes mechanical tunnel ventilation

Inputs and units

Birds per housebirdsbuyer-input
Stocking densitybirds/m²buyer-input
Preferred house widthmbuyer-input

How it is calculated

  • usable production area = birds ÷ scenario density
  • gross floor area = usable area ÷ (1 − 4% service space)
  • length = gross area ÷ width
  • indicative fans = (width × 2.6 m × 2.5 m/s → cfm) ÷ 21,250 cfm per fan at working static pressure

Planning outputs

  • usable production area
  • gross floor area
  • density assumption
  • house length
  • indicative tunnel fan count

Biological assumptions

  • Density is a buyer input; the tool does not select a density for any strain or bird type.

Welfare and regulatory assumptions

  • The entered density must be checked against the binding welfare limit before it is used.

Engineering assumptions

  • Fan sizing assumes a 2.6 m sidewall and a 2.5 m/s target air speed as a screening default.
  • Fan airflow is derated 15% from free-air catalogue capacity to a working static pressure of roughly 25 Pa.

What this tool cannot do

  • A screening layout only — it produces no structural, foundation, drainage or fire design.

What must be confirmed

  • an independent ventilation, structural or electrical engineer
  • the selected equipment supplier or integrator

Tunnel ventilation and fan capacity

v2.0.0 · confidence: medium · reviewed 2026-08-21

Estimate the tunnel airflow and fan count needed to reach a target air speed in a house of known cross-section.

Poultry types: broiler, layer, breeder, turkey · Life stages: all stages requiring tunnel ventilation · Housing: tunnel-ventilated houses · Climate: hot and warm climates; air speed targets rise with heat load

Inputs and units

House widthmbuyer-input
Sidewall heightmbuyer-input
Target air speedm/sbuyer-input

How it is calculated

  • cross-section = width × sidewall height
  • airflow (m³/s) = cross-section × target air speed
  • airflow (cfm) = m³/s × 2118.88 × scenario factor
  • fan count = airflow ÷ (25,000 cfm free air × 0.85 static-pressure derate)

Planning outputs

  • cross-section
  • tunnel airflow (m³/s and cfm)
  • peak airflow required
  • 48-inch fan count at working pressure

Biological assumptions

  • Air speed is a heat-removal target; it does not by itself guarantee any bird performance outcome.

Welfare and regulatory assumptions

  • Minimum air-quality requirements (ammonia, CO2, moisture) are a separate calculation not covered here.

Engineering assumptions

  • Cross-section is a simplified rectangle and ignores trusses, curtains and obstructions.
  • Fans are never sized on free-air capacity; a 15% derate to roughly 25 Pa is applied first.

What this tool cannot do

  • Does not size inlets, does not model static-pressure distribution, and does not cover minimum or transitional ventilation modes.
  • Requires the manufacturer's actual fan performance curve before any purchase decision.

What must be confirmed

  • an independent ventilation, structural or electrical engineer
  • the selected equipment supplier or integrator

Evaporative cooling pad sizing

v2.0.0 · confidence: medium · reviewed 2026-08-21

Estimate pad face area, achievable temperature drop and water flow for an evaporative cooling system.

Poultry types: broiler, layer, breeder · Life stages: all stages in hot weather · Housing: tunnel-ventilated houses with pad cooling · Climate: only useful where the wet-bulb depression is large enough; humid climates are flagged

Inputs and units

Total tunnel airflowcfmbuyer-input
Pad thicknessinchesbuyer-input
Outside design dry-bulb°Cclimate-derived
Outside design wet-bulb°Cclimate-derived

How it is calculated

  • pad face area = airflow (m³/s) ÷ design face velocity (1.5 m/s for 6-inch pads, 2.0 m/s for 4-inch)
  • temperature drop = (dry-bulb − wet-bulb) × pad saturation efficiency
  • inlet temperature = dry-bulb − temperature drop, never below wet-bulb
  • suitability flag raised when the wet-bulb depression is under 6 °C

Planning outputs

  • pad face area
  • pad efficiency
  • inlet air temperature drop
  • humidity suitability verdict
  • water flow

Biological assumptions

  • Cooling relieves heat load; it does not guarantee any mortality, intake or growth outcome.

Welfare and regulatory assumptions

  • Heat-stress management is a welfare obligation and needs an alarm and backup plan, not just pads.

Engineering assumptions

  • Saturation efficiency assumed 75% (6-inch) and 65% (4-inch), to be confirmed against pad manufacturer data.
  • Water flow 3 L/min per m² of pad face while pads run.

What this tool cannot do

  • Evaporative cooling is not assumed suitable in every humidity condition — the tool flags low wet-bulb depression instead of returning a misleading drop.
  • Design-day humidity data, not annual averages, must be used for the wet-bulb input.

What must be confirmed

  • an independent ventilation, structural or electrical engineer
  • the selected equipment supplier or integrator

Heating load

v2.0.0 · confidence: low · reviewed 2026-08-21

Estimate the peak heating load and an indicative brooder count for a house envelope.

Poultry types: broiler, layer pullet, breeder · Life stages: brooding, cold-weather production · Housing: insulated closed houses · Climate: temperate and cold climates, and brooding in any climate

Inputs and units

Envelope aream²buyer-input
Envelope U-valueW/m²Kbuyer-input
Design temperature differenceKclimate-derived

How it is calculated

  • envelope loss = area × U-value × temperature difference
  • total load = envelope loss × 1.2 (minimum-ventilation air exchange allowance) × scenario factor
  • brooders = total BTU/hr ÷ 40,000

Planning outputs

  • envelope loss
  • total heat load (kW and BTU/hr)
  • indicative brooder count

Biological assumptions

  • Brooding target temperatures depend on bird age and strain and are not set by this tool.

Welfare and regulatory assumptions

  • Chilling and overheating are both welfare risks; the design needs controls and alarms, not capacity alone.

Engineering assumptions

  • A flat 20% allowance covers minimum-ventilation heat loss; it does not model infiltration or litter moisture.

What this tool cannot do

  • Not a fuel-sizing, flue, gas-train or fire-safety calculation.

What must be confirmed

  • an independent ventilation, structural or electrical engineer
  • the selected equipment supplier or integrator

Feed demand and storage

v2.0.0 · confidence: medium · reviewed 2026-08-21

Estimate total and per-bird feed for a cycle from a feed conversion assumption and expected mortality.

Poultry types: broiler, layer · Life stages: full cycle · Housing: all · Climate: intake rises in cold weather and falls in heat; not modelled

Inputs and units

Birds placedbirdsbuyer-input
Target live weight or eggs per henkg or eggsbuyer-input
FCR or feed per eggratio or kgstrain-reference
Cycle mortality%buyer-input

How it is calculated

  • survivor feed = birds × (1 − mortality) × target × FCR
  • mortality feed = birds × mortality × target × 0.4 × FCR
  • total feed = survivor feed + mortality feed
  • conservative FCR +0.10; optimistic FCR −0.05

Planning outputs

  • effective FCR
  • survivors
  • total feed (t)
  • feed per bird placed

Biological assumptions

  • A strain guide FCR is a target under guide conditions, never a guaranteed result.
  • Birds lost to mortality are assumed to have eaten 40% of a full cycle's intake, because deaths cluster in early life.

Welfare and regulatory assumptions

  • Feed restriction programmes for breeders are not modelled.

Engineering assumptions

  • Feed wastage, delivery interval and safety stock are not applied; add them before sizing silos.

What this tool cannot do

  • Feed products and feed-mill projects are out of scope and are routed to FeedMatch; only in-house feeding equipment is a HatchMatch scope item.
  • Does not produce a silo volume — bulk density must be stated explicitly for that.

What must be confirmed

  • a poultry veterinarian or production specialist
  • the selected equipment supplier or integrator

Water demand and storage

v2.0.0 · confidence: medium · reviewed 2026-08-21

Estimate daily drinking and cooling water demand and the peak-hour draw-off for storage sizing.

Poultry types: broiler, layer, breeder · Life stages: all · Housing: all · Climate: cooling demand is climate-driven and entered as hot hours per day

Inputs and units

Birds in housebirdsbuyer-input
Water per bird per dayLstrain-reference
Cooling pad face aream²buyer-input
Hot hours per dayhclimate-derived

How it is calculated

  • drinker demand = birds × litres per bird per day × scenario factor
  • cooling demand = pad area × 3 L/min × hot hours × 60
  • peak-hour draw-off = daily drinker demand × 1.5 ÷ 24

Planning outputs

  • drinker demand
  • cooling demand
  • total daily demand
  • peak-hour drinker flow

Biological assumptions

  • Per-bird intake varies sharply with house temperature, age, strain, feed form and water quality.
  • The figure entered is a planning range, not a guaranteed consumption.

Welfare and regulatory assumptions

  • Continuous access to clean water is a welfare requirement; storage must cover supply interruptions.

Engineering assumptions

  • Peak-hour factor 1.5× the daily average.
  • Cooling water at 3 L/min per m² of pad face.

What this tool cannot do

  • Does not size pumps, treatment, line diameters or nipple flow rates.

What must be confirmed

  • the selected equipment supplier or integrator
  • an independent ventilation, structural or electrical engineer

Egg output and grading capacity

v2.0.0 · confidence: medium · reviewed 2026-08-21

Estimate total and peak egg output across a laying cycle for grader and packer sizing.

Poultry types: layer · Life stages: laying period · Housing: cage, aviary, floor · Climate: heat stress reduces output; not modelled

Inputs and units

Hens placedhensbuyer-input
Laying cycle lengthweeksbuyer-input
Average hen-day production%strain-reference
Peak hen-day production%strain-reference
Cycle mortality%buyer-input

How it is calculated

  • average hens present = hens placed × (1 − mortality ÷ 2), i.e. linear depletion
  • total eggs = average hens × cycle weeks × 7 × average HDP
  • peak daily eggs = average hens × peak HDP; where no peak is entered, average + 8 points capped at 96%

Planning outputs

  • effective HDP
  • eggs per hen placed
  • total eggs
  • peak daily eggs

Biological assumptions

  • Hen-day production curves are strain and management dependent; breeder-company objectives are targets, not guaranteed results.
  • Linear depletion is a planning simplification — real mortality is front- and back-loaded.

Welfare and regulatory assumptions

  • Housing system and enrichment requirements affect achievable output and are not modelled here.

Engineering assumptions

  • Grader and packer capacity must be sized on peak daily output, never on the cycle average.

What this tool cannot do

  • Does not apply cracked, dirty or downgraded egg rates unless the calculator page collects them separately.

What must be confirmed

  • a poultry veterinarian or production specialist
  • the selected equipment supplier or integrator

Engineering assumptions

  • Assumes every cycle in the year performs identically.

What this tool cannot do

  • Gross margin only — excludes depreciation, interest, tax, replacement CAPEX and working capital.
  • A calculator output alone never establishes that a project is profitable, viable or bankable.

What must be confirmed

  • an independent financial advisor

  • annual broiler or layer output
  • annual revenue, OPEX and operating profit
  • operating margin and break-even price

Biological assumptions

  • The running-cost extension uses buyer-entered mortality, live weight and FCR; its examples are cross-checked against Ross 308 and Cobb500 objectives but are not guarantees.
  • Layer egg output and livability belong to the layer model and are benchmarked against the Hy-Line Brown performance standards by flock age.

Welfare and regulatory assumptions

  • Housing systems with higher welfare specifications cost more per bird place.
  • Actual mortality and production depend on health, climate, housing, nutrition and management; replace examples with farm records.

Engineering assumptions

  • Excludes land and working capital unless the buyer adds them.
  • Monetary inputs and results use the selected display currency and are normalized through the same daily USD exchange rate.

What this tool cannot do

  • Equipment price is never presented as total project cost.
  • Price examples are not live commodity quotes. Use current local farm-gate or delivered prices; FAOSTAT and USDA ERS are public reference series.
