How to incubate and hatch Coturnix quail eggs successfully — temperature, humidity, turning schedule and hatch-day care for Australian keepers.
Quail eggs are small, fast-developing, and slightly more demanding of precise incubator settings than chicken eggs — the smaller egg mass means less thermal buffering, so temperature and humidity swings affect hatch rates more noticeably. With attention to the details below, Australian backyard keepers can routinely achieve hatch rates of 70 to 85% from fertile eggs.
Selecting and Storing Hatching Eggs
Use eggs from healthy breeding stock, ideally collected within seven days of setting — fertility and hatch rates decline measurably after a week of storage, and more sharply after fourteen days. Store eggs pointed-end down at 12 to 15°C (a cool room rather than the refrigerator, which is too cold) and bring them to room temperature for a few hours before setting in the incubator.
Incubation Settings
| Parameter | Setting |
|---|---|
| Temperature (forced-air incubator) | 37.5°C |
| Temperature (still-air incubator) | 38.6°C (measured at egg height) |
| Humidity (days 1–14) | 45–50% |
| Humidity (days 15–17, lockdown) | 65–70% |
| Incubation period | 16–18 days (typically 17) |
| Turning frequency | 3–5 times daily until lockdown |
Accurate temperature control matters more for quail than for chicken eggs because of their smaller size — even small, brief temperature spikes in a hot Australian shed can affect development. Position incubators away from direct sunlight and in a room with stable ambient temperature, particularly in summer when shed temperatures can swing widely between day and night.
Turning and Candling
Turn eggs at least three times daily (an odd number ensures no two consecutive overnight positions are the same) until lockdown at day 14 or 15, after which turning stops completely. Candle eggs around day 10 to check for development — a developing egg shows visible veining and a dark embryo mass, while a clear egg with no development should be removed to prevent bacterial contamination affecting the rest of the batch.
Lockdown and Hatching
At day 14 to 15, raise humidity to 65–70% and stop turning — this is "lockdown," allowing the chick to position itself correctly for hatching. Do not open the incubator during lockdown except briefly; humidity drops rapidly and can cause the membrane to dry out, a leading cause of chicks failing to hatch despite full development ("shrink wrapping").
Quail typically hatch between day 16 and 18. Resist the urge to assist a slow hatch unless a chick has been visibly struggling for more than 12 hours with no progress — most apparent struggles resolve naturally, and premature assistance causes more deaths than it prevents.
Brooding Newly Hatched Chicks
Leave chicks in the incubator until fully dry and fluffed, then move to a pre-warmed brooder at 37°C for the first week, reducing by about 3°C per week until reaching ambient temperature around week four. Quail chicks are tiny and can squeeze through gaps that would contain chicken chicks — use fine mesh (under 1cm) for brooder walls, and ensure water containers are shallow enough to prevent drowning, which is a common early-life cause of death in quail chicks.
Common Causes of Poor Hatch Rates
The most frequent causes of disappointing hatches in Australian conditions are: incubator temperature fluctuation from poor placement (direct sun, draughty rooms, or near air conditioning vents); humidity too low during lockdown, particularly in dry inland regions where ambient humidity itself is low; eggs stored too long or at incorrect temperature before setting; and insufficient turning frequency in early incubation. Address these systematically and hatch rates typically improve markedly on the next attempt.
