Most duck eggs take 28 days to hatch. Muscovy duck eggs take 35 days to hatch. It is possible for eggs to hatch after anywhere between 25 days and 33 days (or, for Muscovies, between 32 and 38 days).

Duck eggs should be incubated at a temperature between 99.3 and 99.6 (but again, check the setting for your particular model) for 28 days.

Duck eggs incubate at a temperature between 99.3 and 99.6 (but again, check the setting for your particular model) for 28 days.

Incubating duck eggs takes 28 days (35 days for Muscovys) once the eggs have “set”. The eggs are set once they have been in the incubator for 24 hrs.

Incubating duck eggs is similar to incubating chicken eggs, except the incubation period is longer at 28 days and the humidity is slightly higher.
