The short version
| Incubation temp (forced-air) | 99–100°F (37.2–37.8°C) |
|---|---|
| Still-air temp (top of egg) | 101–102°F (38.3–38.9°C) |
| Humidity (days 1–lockdown) | 55–60% |
| Humidity (lockdown–hatch) | 65–70% |
| Total incubation | 28–30 days |
| Lockdown day | Day 26 |
| Candle around | day 10, day 18, day 25 |
Day-by-day schedule
| Day | Phase | What to do | Temp | Humidity |
|---|---|---|---|---|
| Days 1–7 | Incubation | Set eggs large-end up or on their side and turn at least 3–5 times a day (an odd number, or a manual half-turn twice daily on top of an autoturner). Peafowl eggs are large and slow to develop, so keep temperature rock-steady and be patient — visible veining lags behind chicken eggs. | 99–100°F | 55–60% |
| Days 8–14 | Candling | Candle around day 10. Because the shell is thick and buff-colored, veining can be hard to read — look for a spreading network of vessels against the darker embryo. Pull any egg with no development by day 10 so it doesn't spoil. Keep turning and hold humidity. | 99–100°F | 55–60% |
| Days 15–21 | Incubation | Keep turning and hold temperature steady. Candle again around day 18 to confirm the embryo fills more of the egg and the air cell is drawing down. Remove clears and quitters (blood rings / stalled embryos). | 99–100°F | 55–60% |
| Days 22–25 | Incubation | Final turning days. The peachick now fills most of the egg and the air cell should be noticeably enlarged. Do a last candle around day 25 and top up water so humidity doesn't crash right before lockdown. | 99–100°F | 55–60% |
| Day 26 | Lockdown | Stop turning and move the eggs to the hatcher (or lay them on their side in the incubator). Raise humidity to 65–70% and keep the lid closed — opening it now can shrink-wrap a peachick. Breeders who run a GQF setup transfer to a separate hatcher on this day. | 99–100°F | 65–70% |
| Days 27–28 | Hatch | Peachicks internally pip into the air cell, then externally pip the shell. Expect peeping and small cracks. Resist opening the unit — humidity loss stalls hatching siblings and dries out membranes. | 99–100°F | 65–70% |
| Days 29–30 | Hatch | Most peachicks zip and hatch. Leave them to dry and fluff for a day, or until they can stand on their own, before moving to a brooder. Stragglers can arrive a little later, especially from cooler incubators or shipped eggs. | 99–100°F | 65–70% |
Temperature: forced-air vs still-air
In a forced-air incubator (one with a fan) the whole cabinet sits at one temperature, so set it to 99–100°F. Long-time peafowl breeders such as Craig Hopkins of the United Peafowl Association run 99–100°F held consistently throughout, and Mississippi State University Extension gives the same 99–100°F band for forced-air incubation of poultry eggs generally.
A still-air incubator has no fan, so warm air layers near the top. Measure temperature at the top of the eggs and run 101–102°F there — Mississippi State cites 102°F for still-air units. A still-air incubator that reads 99°F at egg-top is actually running cold.
Humidity, wet bulb, and the air cell
Peafowl breeders commonly hold about 60% relative humidity through incubation — roughly an 86–87°F wet-bulb reading — then raise it to 65–70% for hatching. As with any species, the single best check is the air cell: candle weekly and confirm it is enlarging steadily, reaching about a third of the egg by lockdown. Too little air-cell growth means the eggs are too wet; too much means too dry.
Wet-bulb and relative-humidity numbers describe the same thing two ways. If your incubator reports RH, aim for the 55–60% band; if it uses a wet-bulb thermometer, 86–87°F is the equivalent target during incubation.
Turning, candling, and the day-26 transfer
Turn peafowl eggs at least 3–5 times a day until lockdown — many breeders pair an autoturner with a manual 180° turn twice daily. Candle around day 10 to confirm fertility and remove any egg showing no development, then candle again before lockdown to pull clears and quitters. On day 26 stop turning and move the eggs to a hatcher (or settle them on their side), raise humidity, and leave them undisturbed until they hatch on day 28–30.

Dry-hatch vs standard humidity
- Peafowl eggs are frequently 'dry-hatched': humidity is run lower through most of incubation and managed to the air cell rather than to a fixed number, then raised hard at lockdown. Watch the air cell grow to roughly a third of the egg by day 25–26 — candle and adjust to that, not to a thermometer reading alone.
- Because peafowl breed in warm, often humid weather and lay large eggs, over-humid incubation is a common cause of drowned, unabsorbed-yolk chicks. If air cells stay small, lower humidity; if they balloon, raise it.
Shipped eggs
- Let shipped peafowl eggs rest large-end up for 8–24 hours before setting so scrambled air cells can re-settle.
- Peafowl eggs are large and ship poorly; jostled or detached ('saddled') air cells and temperature swings in transit cut hatch rates hard. Set more than you need and expect losses that are about transit, not your incubator.
- If air cells are wobbly or detached, incubate upright in an egg carton for the first week or two and hand-turn gently rather than tumbling them in a turner.
Common pitfalls
- Trusting the incubator's built-in readouts — calibrate against a known-good thermometer and hygrometer before setting valuable peafowl eggs.
- Running humidity too high for the whole cycle; peafowl are especially prone to drowned, sticky, or unabsorbed-yolk chicks when the air cell never grows enough.
- Opening the incubator or hatcher after day 26, which drops humidity and can shrink-wrap a pipped peachick.
- Giving up too early — peafowl take 28–30 days, so a quiet egg on day 28 is normal, not a failure.
Frequently asked questions
- What temperature do I incubate peafowl eggs at?
- 99–100°F in a forced-air incubator, or 101–102°F measured at the top of the eggs in a still-air incubator.
- What day is lockdown for peafowl eggs?
- Around day 26. Stop turning, move the eggs to the hatcher (or lay them on their side), raise humidity to 65–70%, and keep the unit closed until they hatch on day 28–30.
- How long do peafowl eggs take to hatch?
- 28–30 days, about 29 on average. A few peachicks may arrive a little later, especially if the incubator ran slightly cool or the eggs were shipped.
- What humidity do I need for hatching peafowl eggs?
- Around 55–60% (about an 86–87°F wet bulb) for most of incubation, then 65–70% from lockdown through hatch. Use the air-cell size as your real guide — it should reach roughly a third of the egg by day 26.
- When should I candle peafowl eggs?
- Candle around day 10 to check fertility and pull any egg with no development, then again around day 18 and day 25 to remove clears and quitters and to watch the air cell grow before lockdown.
- How often should I turn peafowl eggs?
- At least 3–5 times a day until lockdown — commonly an autoturner plus a manual 180° turn twice daily. Stop turning at lockdown around day 26 so the peachick can settle into hatching position.
