If on the other hand you use an incubator in order to hatch fertilized chicken eggs, they can sometimes hatch a day or two early, or they can also hatch out a few days late. Things like humidity and temperature play a significant role.
How Long Does Hatching Take. Hatching can take place over several days. For chickens, run the incubator for 24 days (3 days more than normal hatch time). For ducks and turkeys run the incubator for 32 days (4 days more than normal hatch time). It is better not to help a chick/duckling/poult crack out of its shell. If you do, they almost always die (unless you follow the instructions in the next paragraphs).
