How to use this duck egg incubation calculator

Choose the date the eggs were placed in the incubator or under a broody duck, then pick the duck type that best matches your eggs. The calculator adds the incubation length to estimate hatch day and works backward to show lockdown.

Use the 28-day setting for common domestic duck breeds such as Pekin, Rouen, Khaki Campbell, Indian Runner, Welsh Harlequin, and Cayuga. Use the 35-day setting for Muscovy eggs.

Duck egg incubation reminders

Duck eggs often benefit from steady temperature, careful humidity management, regular turning before lockdown, and clean handling. Follow your incubator instructions and avoid opening the incubator during the final hatch window unless necessary.

FAQ

Do duck eggs always hatch exactly on day 28?

No. Day 28 is the common target for many domestic ducks, but hatch can be early or late depending on breed, temperature stability, egg age, humidity, fertility, and handling.

Are Muscovy duck eggs different?

Yes. Muscovy duck eggs usually take about 35 days instead of 28 days. Select the Muscovy option to get the longer hatch timeline.

When should I stop turning duck eggs?

For most duck eggs, stop turning at lockdown, usually about three days before the expected hatch. The calculator shows this date based on the incubation length you choose.
