How long does it take for a chicken egg to hatch?
Baby peeps will hatch from their eggs about 21 days after they begin the incubation period. In an incubator, this number can be easily monitored. However, when a laying hen who hatches her own eggs, she will first lay a clutch over a period of a couple weeks and then begin sitting on them all at the same time. Thus the amount of time it takes for the chicken egg to hatch is longer when accounting for the days after it is laid before the hen begins the sitting, or 21-day natural incubation, process.
