Incubator marketing is almost all about capacity and the display. Hatch rates are almost all about two other things: whether the air moves, and whether the eggs get turned.
Get those right and a cheap box hatches well. Get them wrong and an expensive one does not.
The 21 days, in the order they happen
| Days | Temperature | Humidity | Turning | What you do |
|---|---|---|---|---|
| Setting | 99.5°F forced air | ~50% | Start | Let the incubator stabilise 24h first |
| 1–7 | 99.5°F | ~50% | 3–5x daily | Candle at day 7, remove clears |
| 8–14 | 99.5°F | ~50% | 3–5x daily | Candle at day 14 if you like |
| 15–18 | 99.5°F | ~50% | 3–5x daily | Top up water from outside if you can |
| 18 (lockdown) | 99.5°F | 65%+ | Stop | Remove the turner, lay eggs on their side |
| 19–21 | 99.5°F | 65%+ | None | Do not open the lid |
| 21+ | 99.5°F | 65%+ | None | Leave chicks 24h before moving to the brooder |
Lockdown is where most hatches are lost, and always in the same way: the lid comes off to help a struggling chick, humidity crashes, and the membrane dries onto the chicks still inside.
Watch out
From day 18, keep the lid closed even when it is hard to watch. A hatch can take over 24 hours from the first pip, and the chicks behind the one you can see are the ones that pay for opening.
Why your own thermometer is the best thing you will buy
The display on a budget incubator reads whatever its sensor says, wherever that sensor sits — often near the heating element or in the lid, not at egg height. A unit displaying a confident 99.5 while actually holding 101.5 at the top of the eggs will produce early hatches, leg problems and a lot of dead-in-shell.
Two cheap independent gauges at egg height, cross-checked against each other, cost a fraction of the incubator and tell you what is actually happening. If they disagree with the display, believe them.
Still air, and why it spreads your results
In a still-air box, warm air rises and sits at the top. The consequence is that the top surface of an egg is warmer than the bottom, and an egg at the edge of the tray is at a different temperature from one in the middle.
So you do not get a single hatch — you get a spread. Some chicks come early, some late, some not at all, and nothing you did explains the pattern. A fan costs very little and removes the whole problem, which is why forced air is the first thing to look for and not an upgrade.
The part to decide before you buy anything
A hatch is 21 days of mild attention. What follows is six to eight weeks of brooder: heat, bedding changed constantly, feed, water, space, and the smell of a brooder in a utility room.
And about half of what hatches will be cockerels. In most residential areas a cockerel is either not permitted or not tolerated, which means finding homes for birds few people want, or dispatching them yourself.
None of that is a reason not to hatch — it is genuinely one of the better things to do with a spring. But if the goal is simply more eggs, point-of-lay pullets cost less, arrive sexed, and start laying in weeks rather than months.
How we picked
Judged on published specifications, the features that hatch-rate research identifies as decisive, and what owners report over multiple hatches — nothing here was tested in our own incubator. · Picks last checked October 2026.
- Temperature stability, not the set point
- Every incubator reaches 99.5°F. What separates them is how far it drifts when the room cools overnight, and drift is what kills embryos.
- Forced air, not still air
- A fan evens the temperature across the whole tray. In a still-air box the top of the egg can run degrees warmer than the bottom, and hatch rates spread accordingly.
- Automatic turning
- Eggs need turning several times a day for 18 days. Hand-turning works and is reliably forgotten — this is the feature that most changes real-world results.
- Humidity you can actually control
- Around 50% for the first 18 days and 65%+ for the hatch. A visible water channel you can top up without opening the lid is worth more than a digital readout you cannot act on.
- Can you see in without opening it
- Every lid-lift drops temperature and humidity. A clear top is a hatch-rate feature, not a convenience.

Best overall for a backyard flock
Mid-range forced-air digital with automatic turner
The right first incubator. Buy it, then buy a separate thermometer and hygrometer and trust those instead of the display.
- Capacity
- Typically 12–24 hen eggs
- Air
- Forced (fan)
- Turning
- Automatic
- Display
- Digital temperature and humidity
- Extras
- Clear lid, external water fill
What we liked
- Forced air evens temperature across the whole tray
- Automatic turning removes the commonest beginner failure
- Clear lid means you can watch without dropping humidity
- External water fill avoids opening during lockdown
Worth knowing
- Built-in readouts are often a degree or two out of calibration
- Thin plastic shells hold temperature poorly in a cold room
Best value
Small forced-air digital with turner
Good value if the room is warm and stable. Keep it out of a garage or a conservatory.
- Capacity
- 7–12 hen eggs
- Air
- Forced (fan)
- Turning
- Automatic
- Display
- Digital
- Extras
- Clear dome
What we liked
- Cheapest unit that still has both features that matter
- Small batch suits a backyard flock's actual needs
- Quick to come up to temperature
- Easy to clean between hatches
Worth knowing
- Low thermal mass, so room temperature swings show up inside
- A failed hatch wastes the whole small batch
Best for regular or staggered hatches
Cabinet incubator
Buy it if you hatch every year or sell chicks. Overkill for one spring hatch of a dozen eggs.
- Capacity
- 40–200+ hen eggs
- Air
- Forced
- Turning
- Automatic, whole-rack
- Display
- Digital with alarms
- Extras
- Insulated cabinet, separate hatching tray
What we liked
- Heavy thermal mass rides out cold nights and brief power cuts
- Takes staggered batches, so you can set eggs weekly
- Separate hatcher tray keeps mess away from incubating eggs
- Lasts years and holds resale value
Worth knowing
- Several times the price of a tabletop unit
- Large and heavy, and needs a permanent spot
- Far more capacity than most backyard flocks need
The accessory that decides the hatch
Separate calibrated thermometer and hygrometer
The highest-return purchase on this page relative to its cost. An incubator running 2°F hot while displaying correctly hatches almost nothing.
- Measures
- Temperature and relative humidity
- Placement
- At egg height, not on the lid
- Why
- Independent check on the built-in readout
- Cost
- A small fraction of the incubator
What we liked
- Catches a miscalibrated display before it costs you a hatch
- Reads at egg height, where it matters, not at the lid
- Works in any incubator, including a home-made one
- Cheap enough to buy two and compare
Worth knowing
- One more thing inside the chamber
- Cheap units can themselves be inaccurate — buy two
Best for knowing what is developing
Candling lamp
Worth owning. Candle at day seven, pull the clears, and stop opening the incubator after day 18.
- Use
- Checking fertility and development at day 7 and 14
- Type
- Bright cold LED
- Works on
- Pale and tinted shells; poorly on very dark eggs
- When
- Briefly, in a dark room
What we liked
- Lets you pull clear and dead eggs before they spoil
- Turns a 21-day wait into something you can follow
- A rotten egg removed is a burst egg avoided
- Cheap and lasts indefinitely
Worth knowing
- Nearly useless on dark brown or olive eggs
- Over-candling means repeated cooling
Which should you buy?
Our verdict
- Best overall:
- Mid-range forced-air digital with automatic turner
- Best value:
- Small forced-air digital with turner
Spend on forced air and an automatic turner, and almost nothing else. Those two features fix the two failure modes that actually lose hatches — uneven heat across the tray, and a turning schedule nobody keeps. Then buy a separate calibrated thermometer and hygrometer, because the built-in readouts on budget units are frequently several degrees out, and an incubator that holds 101.5°F while displaying 99.5°F will hatch almost nothing.
| If you… | Buy | Because |
|---|---|---|
| First hatch, a dozen eggs, want it to work | A mid-range forced-air digital with an automatic turner | Forced air plus automatic turning removes the two biggest sources of beginner failure in one purchase. |
| Hatching regularly, or selling chicks | A cabinet incubator | Far better thermal mass means it holds temperature through a power blip or a cold night, and it takes staggered batches. |
| Tight budget, and you are home all day | A small forced-air without a turner | You can hand-turn three to five times a day. Mark each egg X and O so you know what you turned. |
| Children and a school-project hatch | A small clear-domed digital with a turner | You can watch the whole hatch without opening it, which is both the point and better for the eggs. |
| Shipped or valuable eggs | The most thermally stable unit you can afford, plus a separate thermometer | Shipped eggs already hatch poorly. Do not add equipment drift to the handicap. |
When not to buy at all
Do not buy an incubator before you have somewhere for the chicks to go. A hatch is 21 days; a brooder is six to eight weeks, and roughly half of what hatches will be cockerels you may not be allowed to keep. If you want a few more hens, buying pullets is cheaper, faster and far less work than hatching. And skip the very cheapest still-air styrofoam boxes with no fan: they hatch something, and the disappointment of a 20% hatch is what stops most people trying again.
