Goose incubation guide
How long do goose eggs take to hatch?
Goose eggs take about 30 days to hatch. Most hatch between day 28 and day 34, depending on breed and how steady the incubator temperature was. Breed shifts the date by a few days, which is why the calculator asks for it.
Quick rule: Count 30 days from the day you set the eggs. Lockdown starts 3 days before that.
How to use the goose egg incubation calculator
1. Enter the date eggs were set. The day the eggs went into the incubator or under the goose. Tap Use today if it was today.
2. Pick the breed. The whole window moves with the breed average.
Then follow the schedule. Each task gets a real date, the next one is highlighted, the status shows whether goose eggs are on track, and the day by day cards above show where things stand. Use Copy schedule or Add to Google Calendar to keep it.
Hatch date formulas
- Estimated hatch date = date eggs were set + 30 days
- Earliest normal hatch = date eggs were set + 28 days
- Latest normal hatch = date eggs were set + 34 days
- Lockdown = hatch date minus 3 days
- Candle any unhatched eggs if nothing has happened by day 35
Hatch schedule at a glance
| When | Task | Why |
|---|---|---|
| Day 10 | First candling | Remove clear eggs that show no veins. Fertile eggs show veins and a dark spot. |
| Day 20 | Second candling | Remove eggs that stopped developing. Look for no movement or a blood ring. |
| 3 days before hatch | Lockdown | Stop turning, raise humidity to about 75 to 80 percent, and keep the lid closed until hatching is over. |
