Swans are majestic birds raised for ornamental, conservation, and eco‑tourism purposes. Successfully hatching swan eggs requires patience, precision, and proper incubation conditions.
A swan egg incubation period lasts 34–40 days, which is much longer than chickens, ducks, or geese. Mistakes in temperature, humidity, egg turning, or ventilation can lead to embryo death or weak cygnets.
❌ Early embryo death
❌ Weak or deformed cygnets
❌ Late hatching or failed pipping
This step‑by‑step swan egg hatching guide will help you:
✅ Increase hatch success rates
✅ Raise stronger, healthier cygnets
✅ Avoid common incubation problems
📅 Day‑by‑Day Swan Egg Hatching Life Cycle
🐣 Day 1–3: Early Embryonic Development
- The fertilized egg begins forming the heart, spinal cord, and blood vessels.
- Maintain incubator temperature at 99.3°F (37.4°C) and humidity at 50–55%.
- Turn eggs 3–5 times daily to prevent embryo adhesion.
💡 Tip: Swans lay large eggs, so ensure the incubator has proper space and even heat distribution.
🐣 Day 4–7: Heartbeat and Blood Vessel Growth
- The embryo's heartbeat becomes active.
- Candling at Day 7 shows a visible blood ring and eye spot.
- Continue regular turning and ventilation.

🐣 Day 8–14: Organ and Limb Formation
- Major organs such as liver, lungs, and limbs begin developing.
- Embryo size increases; stable temperature and humidity are critical.
- Avoid frequent incubator opening to prevent heat and humidity loss.
🐣 Day 15–21: Rapid Growth and Feather Follicles
- The beak hardens, claws form, and feather follicles become visible.
- Oxygen demand gradually increases.
- Continue turning eggs at least 3 times per day.
🐣 Day 22–28: Advanced Organ Development
- The embryo now occupies most of the egg.
- The yolk sac becomes the main source of nutrition.
- Maintain proper ventilation to ensure oxygen flow.
🐣 Day 29–32: Pre‑Hatch Stage Preparation
- Gradually reduce egg turning.
- Increase humidity to 65–70% to prevent membrane shrink‑wrapping.
- Lower temperature slightly to 99°F.
🐣 Day 33–40: Pipping and Hatching
- Cygnets pip the shell (external breathing begins).
- Do not open the incubator during pipping, as sudden humidity loss can trap chicks.
- After hatching, leave cygnets in the incubator for 10–12 hours to dry and strengthen.
🔧 Swan Incubation Requirements
| Parameter | Setting |
|---|---|
| Temperature | 99.3°F (37.4°C) |
| Humidity (early) | 50–55% |
| Humidity (lockdown) | 65–70% |
| Egg Turning | 3–5 times/day until Day 29 |
| Ventilation | Increase gradually from Day 15 onward |
🧠 Advanced Swan Hatching Tips
✅ Always use fresh, fertile eggs (not older than 10 days) for best results.
✅ Candle at Day 7 and Day 21 to remove infertile eggs.
✅ Use a reliable incubator with auto‑turner for large eggs.
✅ Ensure power backup in case of outages (important for long incubation periods).
🔬 Weekly Embryo Growth Chart
| Week | Key Development Stage |
|---|---|
| 1 | Heartbeat starts, blood vessels form |
| 2 | Eyes, beak, wings, and legs develop |
| 3 | Feather follicles appear, organs mature |
| 4 | Embryo fills most egg space |
| 5 | Final growth, chick positions to hatch |
| 6 | Pipping and hatching |
⚠️ Common Problems and Solutions
| Problem | Cause | Solution |
|---|---|---|
| Dead embryos mid‑way | Incorrect temperature or turning | Calibrate incubator, turn eggs regularly |
| Weak or deformed cygnets | Low humidity or poor ventilation | Increase humidity, improve airflow |
| Late or failed pipping | Improper humidity during lockdown | Maintain 65–70% humidity consistently |
| Unhatched eggs | Infertile or contaminated eggs | Candle early and discard non‑viable eggs |

| Brooder Setup | $100–$300 | For cygnet care after hatching |
📈 Tips to Improve Swan Hatch Rates
✅ Use fresh, fertile eggs (not older than 10 days).
✅ Candle eggs on Day 7, 14, and 21.
✅ Avoid frequent incubator opening.
✅ Keep power backup ready for outages.
🐤 Caring for Cygnets After Hatching
- Move cygnets to a brooder at 90–95°F for the first week.
- Provide clean water and high‑protein starter feed.
- Gradually reduce brooder temperature by 5°F weekly.
- Swans need access to shallow water after 3–4 weeks but must be supervised.
📌 Final Thoughts
Swan egg hatching is a long and delicate process requiring patience, precision, and proper incubation care. Following a day‑by‑day hatching guide, correct temperature, humidity control, and post‑hatch cygnet care ensures healthy, strong swans and high hatch success rates.
