Whereas fertilized chicken eggs usually take exactly 21 days to hatch, most duck eggs take 28 days, apart from Muscovy ducks. As a general rule of thumb, the eggs of Muscovy ducks take 35 days, but once again, it can vary slightly depending on conditions.
Plan ahead of time. Duck eggs usually take 28 days to hatch, but some breeds take as long as 35 days. You need to make sure that your incubator is prepared in advance before you purchase duck eggs and attempt to hatch them. Duck eggs are larger than chicken eggs, so many chicken egg incubators will not accommodate duck eggs.
