Fix capacity and principle first
Eggs set per week and the incubation principle determine machine count, room layout and building size. Changing either after award is expensive.
- Eggs set per week now, and the phase-two capacity the building should allow
- Single-stage or multi-stage, with the reason stated (flexibility, biosecurity, energy, existing fleet)
- Setter and hatcher capacities and the resulting machine count
- Hatch pattern: how many set days and hatch days per week
- Breed and expected hatchability, since these drive chick output not egg input
The HVAC boundary is the decisive line
Incubators reject a large heat load into the room. If no bidder owns the room, the hatchery will not perform whatever machines are installed.
- Who sizes and supplies setter room, hatcher room, chick processing and corridor HVAC
- Design airflow, fresh air rate and pressure cascade between rooms
- Cooling load basis: outdoor design conditions used, and redundancy assumed
- Humidification and dehumidification scope
- Filtration grade at each stage and biosecurity separation of clean and dirty flows
- Standby power: which loads are backed up and for how long
Chick handling and the rest of the flow
Machines are one package; the flow from egg receipt to chick dispatch is the project.
- Egg receipt, storage and pre-warming rooms
- Traying, transfer and candling equipment, manual or automated
- Chick take-off, counting, vaccination, sexing and box filling
- Waste handling: eggshells, unhatched eggs and dead-on-arrival flow
- Washing area for trays, buggies and boxes
- Hatchery management software, data logging and traceability
Hatchery bid comparability check
| Item | Comparable when | Not comparable when |
|---|---|---|
| Capacity | Eggs set per week identical across bids | Chick output compared against egg intake |
| Principle | All bids single-stage or all multi-stage | Mixed principles in one comparison |
| HVAC | Same rooms, same design conditions, same bidder scope | One bid excludes room HVAC entirely |
| Standby power | Same backed-up load list and duration | Generator excluded by the machine supplier |
| Chick handling | Same automation level to the same end point | Manual take-off compared with automated |
| Software | Same modules and licence duration | Software quoted as an option in one bid |
Comparable means every bidder priced the same duty, the same design conditions and the same delivery point. Where a column is blank in a real offer, treat it as excluded until the supplier confirms otherwise in writing.
Hatchery RFQ readiness checklist
- Eggs set per week and phase-two capacity written down
- Single-stage or multi-stage decided and justified
- Hatch pattern and working week defined
- HVAC responsibility boundary stated explicitly in the RFQ
- Outdoor design conditions and altitude attached
- Room list and clean/dirty flow diagram attached
- Standby power scope and backed-up load list defined
- Chick handling automation level defined to a named end point
- Commissioning, hatch-result acceptance criteria and training days stated
Lifecycle cost
Lifecycle cost drivers in hatchery equipment bids
In a hatchery the largest operating cost is usually not the incubators — it is the room HVAC that removes the heat the machines reject. Lifecycle comparison only works when every bid carries the same HVAC boundary, which is why the boundary comes first in this guide.
Cost drivers that outlast the purchase price
- HVAC energy: machines reject a continuous heat load into the rooms; room cooling is usually the largest single operating cost and the most common scope gap.
- Machine energy per 1,000 eggs set: single-stage and multi-stage fleets differ — demand the figure at your room conditions, not at reference conditions.
- Standby power: which loads are backed up changes generator CAPEX and the cost of every outage hour.
- Consumables and wear: door seals, sensors, fan motors and humidifier parts have fixed replacement intervals.
- Software licences: hatchery management and traceability renewals are an annual operating line, not a one-off.
Request these inputs from every bidder
- Expected kWh per 1,000 eggs set per year at stated room temperature and humidity conditions
- Room HVAC connected load, and written confirmation of whether it sits inside or outside the bid
- Annual maintenance contract price and what it excludes
- Wear-part intervals and prices: seals, sensors, motors, humidifier components
- Software licence renewal cost per year after the included period
- Delivered lead time, installation duration and commissioning period in weeks
Worked example — hypothetical figures, calculator arithmetic
| Metric | Bid A | Bid B |
|---|---|---|
| Quoted CAPEX | 8,900,000 | 7,600,000 |
| Energy (10 yr) | 570,000 | 750,000 |
| Maintenance + spares (10 yr) | 2,980,000 | 3,476,000 |
| Lead-time delay cost | — | 360,000 |
| Total lifecycle cost (10 yr) | 12,450,000 | 12,186,000 |
| Per 1,000 eggs set | 24,900 | 24,372 |
| Per 1,000 eggs set per year | 2490.00 | 2437.20 |
Illustrative only: two hypothetical bids in one shared currency. Assumptions: 10-year horizon, electricity 0.12 per kWh, no escalation or discounting, delay costed at 60 per 1,000-eggs-set of weekly capacity per week beyond the faster offer.
