Chicken vs Quail Eggs: The BIG Differences in Incubation (and Other Game Bird Eggs)
Mixed Hatch? Here’s How Chicken and Game Bird Eggs Incubate Differently
If you’ve only ever incubated chicken eggs, your first batch of quail or game bird eggs might come as a surprise.
They look different.
They hatch differently.
And they definitely need different humidity timing.
For Gone Broody customers running mixed hatches — especially chickens, quail, pheasants, ducks, turkeys, or even peafowl — this is where things can quietly go wrong. Incubation settings that work for chicken eggs are often too forgiving for small game bird eggs.
Let’s walk through the real differences between:
- Chickens
- Quail
- Partridge
- Pheasants
- Turkeys
- Ducks
- Geese
- Peacocks
Hatch Time: Not All Eggs Run on the Same Clock
| Bird Type | Average Hatch Time |
|---|---|
| Chickens | ~21 days |
| Coturnix Quail | ~16–18 days |
| Bobwhite Quail | ~23 days |
| Partridge | ~23–25 days |
| Pheasant | ~24–25 days |
| Turkey | ~28 days |
| Duck | ~28 days |
| Goose | ~30–32 days |
| Peacock | ~28–30 days |
Quail hatch faster — which sounds convenient… until you realize it gives you less time to correct mistakes.
A humidity issue that chickens might tolerate for a day or two can dry out a Coturnix egg quickly enough to cause shrink-wrapping before you even know there’s a problem.
Can You Incubate Different Species in the Same Incubator?
Short answer: Yes… but only if you plan for it.
Different species require:
- Different humidity levels
- Different lockdown dates
- Different total incubation times
If you place chicken eggs and Coturnix quail eggs into the incubator on the same day, the quail will enter lockdown on Day 14 while your chicken eggs still need turning until Day 18.
That creates a real problem.
Once you raise humidity for quail lockdown, it can:
- Slow proper air cell development in chicken eggs
- Cause excess moisture retention
- Lead to late hatch failures or drowned embryos
Opening the incubator repeatedly to remove early hatchers can also drop humidity enough to shrink-wrap later-developing species like ducks, turkeys, or geese.
Mixed Hatch Recommendations
If you're planning to hatch multiple species together, follow these best practices:
- Stagger your set dates. Add longer-incubating species first (goose, duck, turkey), followed by chickens, then quail last.
- Aim for a shared lockdown date. Try to have all species reach lockdown within 24–48 hours of each other.
- Use separate hatchers if possible. Many experienced keepers incubate together but hatch separately.
- Monitor air cell size instead of relying on preset humidity. Mixed species lose moisture at different rates.
- Limit incubator openings during hatch. Later-developing species are vulnerable to membrane drying.
This is especially important for:
- Quail (fast hatchers)
- Geese (long hatchers)
- Ducks (higher humidity needs)
- Peacocks (sensitive late hatch phase)
Why Smaller Eggs Are Less Forgiving
Coturnix quail, partridge, and other small game bird eggs have:
- Thinner shells
- Higher surface-area-to-volume ratio
- Faster moisture loss
That means:
- Humidity swings hit harder
- Air cells grow faster
- Embryos can dehydrate more easily
Larger eggs — like duck, turkey, goose, or peacock eggs — develop more slowly, which gives you a wider buffer to catch problems early. But they often require higher baseline humidity throughout incubation due to thicker shells and longer development time.
Recommended Incubation Humidity by Species
| Bird Type | Days 1–Lockdown | Lockdown Humidity | Lockdown Begins |
|---|---|---|---|
| Chickens | 40–50% | 65–70% | Day 18 |
| Coturnix Quail | 35–45% | 65–70% | Day 14 |
| Bobwhite Quail | 45–50% | 65–70% | Day 20 |
| Partridge | 45–50% | 65–70% | Day 21–22 |
| Pheasant | 45–50% | 65–70% | Day 21–22 |
| Turkey | 45–55% | 65–75% | Day 25 |
| Duck | 50–55% | 70–75% | Day 25 |
| Goose | 55–60% | 75–80% | Day 27–28 |
| Peacock | 45–55% | 65–75% | Day 25–26 |
Lockdown = stop turning eggs and increase humidity.
This is when the chick, poult, or keet begins positioning to hatch — and when humidity becomes critical for preventing membranes from drying out during pip.
Don’t Trust Your Incubator’s Built-In Reading Alone
Many incubators — even good ones — can have humidity readings that are off by 5–10%.
That’s enough to impact a small egg.
We strongly recommend placing a separate digital thermometer/hygrometer at egg level inside the incubator so you know your actual conditions, not just the machine’s estimate.

The Takeaway
Chicken eggs are a great place to start.
But once you move into quail, pheasant, partridge, turkey, duck, goose, or peacock eggs… incubation becomes less about time — and more about precision.
Not all incubators are built for small game bird eggs.
