Whereas fertilized chicken eggs usually take exactly 21 days to hatch, most duck eggs take 28 days, apart from Muscovy ducks.
This usually results in a 58-60 day incubation period and large, robust hatchlings. You can incubate at a slightly higher temperature for a slightly shorter incubation (55 days or so), but you have to be careful that the clutch doesn't overheat once the eggs start generating heat.
