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.
Most breeds require about 28 days of incubation. The similarities in hatching duck eggs to other eggs are that you need the same temperature (about 99.5 degrees F), the duck eggs need to be turned and you'll need a safe environment for them. A duck incubator can be the same incubator you use for other eggs.So if you already hatch chicken eggs and you want to try hatching duck eggs, you'll likely already have everything you need.he Hova-Bator and Little Giant incubators work great for incubating all breeds of duck. The Hova-Bator and Little Giant with universal/chicken egg racks accommodate duck eggs nicely. Each turner can hold up to 41 duck eggs. All of our combo kits also work great with duck eggs.
