Hatch Results Falling? Run a Breakout Before You Budget for New Incubators
A breakout of unhatched eggs is the cheapest evidence a hatchery can collect. Use it to decide whether the upgrade budget belongs in machines, the egg store, or nowhere yet.

In short
Short answer: a hatch breakout (opening and classifying unhatched eggs after a hatch) tells you *when* embryos were lost. Losses before or very early in development usually lead the investigation toward breeder flock, fertility and egg handling. Losses later in incubation lead it toward setter, hatcher and room conditions.
Key takeaways
- Consistent sampling across several hatches matters more than the size of any single breakout.
- Classifying losses by embryo stage shows whether the investigation belongs with the breeder flock, the egg store or the machines.
- A suspected machine problem should be confirmed with calibrated temperature and humidity logging across tray positions for several cycles.
- Turkey and duck eggs have different incubation periods, egg sizes and climate needs from chicken eggs.
- Each breakout pattern points to a different scope, and only machine-stage patterns usually justify an incubation upgrade.

Losses before or very early in development usually lead the investigation toward breeder flock, fertility and egg handling. Losses later in incubation lead it toward setter, hatcher and room conditions. Only the second pattern makes an equipment upgrade a likely answer. Breeder companies publish step-by-step breakout methods: Aviagen's breakout how-to for chickens and Aviagen Turkeys' breakout guide for turkeys.
Definition — hatchability: the share of eggs set (or of fertile eggs set) that produce a saleable chick or poult. Always state which denominator you use; mixing them makes comparisons between hatcheries meaningless.
Step 1: Sample consistently
Consistent sampling across several hatches matters more than the size of any single breakout.
- Break out residue from the same machines, flock sources and egg ages over several hatches, not one bad day. - Record flock age, egg storage days, setter and position, and transfer time for every tray sampled. - Use one classification sheet across staff so categories stay comparable.

Start freeStep 2: Classify by stage, then by pattern
Classifying losses by embryo stage shows whether the investigation belongs with the breeder flock, the egg store or the machines.
| Pattern seen in breakout | Investigate first | Equipment likely relevant? |
|---|---|---|
| Many clear eggs that show no development | Fertility, breeder management, egg storage | Rarely — egg store only if storage climate is unstable |
| Early embryo losses | Egg handling, storage time and temperature, fumigation | Egg store climate, pre-warming facilities |
| Mid-incubation losses | Setter temperature, turning, ventilation | Setter controls, turning, airflow |
| Late losses, pips not hatched | Setter/hatcher temperature and humidity, transfer handling | Hatcher climate, transfer equipment |
| Losses clustered in one machine or tray position | Uniformity within that machine | Strong signal for machine service or replacement |
Step 3: Confirm with logged data
A suspected machine problem should be confirmed with calibrated temperature and humidity logging across tray positions for several cycles. Spot readings from the controller display do not show uniformity. If one machine logs consistently outside its peers, quote a service or retrofit before a replacement.
Step 4: Species changes the reference
Turkey and duck eggs have different incubation periods, egg sizes and climate needs from chicken eggs. Use the species-specific guidance — for example Aviagen Turkeys' hatchery management guidelines — and never benchmark a turkey or duck hatchery against chicken figures.
Step 5: Turn the finding into a scope
Each breakout pattern points to a different scope, and only machine-stage patterns usually justify an incubation upgrade.
- Egg-stage pattern: fix storage and handling first; equipment scope, if any, is the egg store. - Machine-stage pattern: scope setter/hatcher service, controller retrofit or replacement — compare options in our incubation approaches comparison. - Ready to buy: use the procurement checklist and the problem guide low hatchability — hatchery upgrade.

Frequently asked questions
How many eggs should a breakout include? Breeder-company guides describe sampling methods; follow the one for your species and keep it consistent between hatches so trends are comparable.
Can a breakout prove the incubator is faulty? No. It points to a stage; logged temperature and humidity uniformity is what confirms a machine problem.
Does HatchMatch analyse breakouts? No. We help you turn a confirmed scope into a comparable RFQ. Every brief gets human review, and we aim to reply within two business days.
