How long does a hen egg take to hatch?

Answer 1

Chicken eggs require 21 days at 101F to hatch. When trying to hatch chicken eggs, give them a few extra days before throwing out eggs that have not hatched as they may have been cold and needed a day or so to come up to incubation temperature.

Answer 2

It takes 21 days from the time the broody hen begins to sit and stay on the clutch of eggs. When incubating a clutch of fertilized eggs artificially, breeders collect eggs for up to seven days and start them all at the same time. 21 days from the date they are first set into the incubator at 100.5 degrees F with a relative humidity of +50% will produce a hatch.

Answer 3

A hen egg typically takes around 21 days to hatch, but this can vary slightly depending on the breed of the chicken and the specific incubation conditions.
