Chicken eggs typically take about 21 days to hatch after incubation begins

. Key details about the hatching process:

  • The incubation period is usually 20 to 21 days for chicken eggs, though it can vary slightly depending on factors like flock age and egg storage
  • During the first 18 days, eggs should be turned several times a day to prevent the embryo from sticking to the shell
  • From day 18, turning stops and humidity is increased to around 65-70% to prepare for hatching
  • Chicks start pipping (breaking the shell) around day 20 and usually hatch on day 21, but the process can take up to 24 hours
  • If eggs have been stored or cooled before incubation, hatching might take a little longer
  • After hatching, chicks remain in the incubator until dry and fluffy before being moved to a brooder

In summary, the standard incubation and hatching time for chicken eggs is about 21 days, with careful temperature and humidity control critical for success
