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.
The eggs of most ducks -- including Indian Runners, Call Ducks and Pekins -- take about 26 to 28 days to hatch, while Muscovies require approximately 35 days. After the first 24 hours, you'll need to turn the eggs in your incubator three times daily to exercise the embryo and relieve stress. Around days seven, 12, 19 and 24, you'll remove each egg individually long enough to candle them -- shine a bright light through each egg to look for veins.
