Whereas fertilized chicken eggs usually take exactly 21 days to hatch, most duck eggs take 28 days, apart from Muscovy ducks.
Eggs do not necessarily hatch uniformly and this is more noticeable in species that have a long gestation period (perhaps 4 weeks). The first (usually an uppermost member) to hatch can be 10 days or more in front of the main group, with some taking noticeably longer.
