Whereas fertilized chicken eggs usually take exactly 21 days to hatch, most duck eggs take 28 days, apart from Muscovy ducks.
The incubation period varies by species and generally takes about a month. When the ducklings begin to crack through their shells at the end of the incubation period, they should all hatch within 24 to 48 hours.
