Duck Egg Incubation
Duck egg timing, candling, lockdown, air-cell checks, and moisture management.
The hatch looks familiar to chicken keepers, but duck eggs ask for a different calendar and closer moisture attention.
Quick Answer
Most domestic duck eggs hatch around 28 days, with lockdown commonly around day 25. Muscovy ducks are different and usually need a longer schedule.
This page is practical hatch guidance, not a veterinary diagnosis. It is checked against the sources listed below and should be adjusted to your incubator manual, species, and local conditions.

What matters most
- Most duck eggs use a 28-day schedule.
- Move most duck eggs toward hatch conditions around day 25.
- Muscovy duck eggs commonly take longer than other domestic duck eggs.
- Watch air-cell growth instead of relying only on a humidity number.
Use the duck calendar, not the chicken calendar
Duck eggs are commonly managed on a 28-day incubation plan. That changes candling, turning, and lockdown timing compared with chicken eggs.
Air-cell development tells the real moisture story
Duck eggs can vary by breed, shell, and incubator airflow. Candling gives a practical view of whether moisture loss is moving in the right direction before hatch.
Separate Muscovy plans
Muscovy duck eggs are a common exception and need a longer plan. Do not mix Muscovy timing into a standard duck hatch calendar without adjusting dates.
