Are you wanting better eggs for your family?
It usually takes 21 days for a chicken egg to fully incubate.
A day is the full 24 hours after you put the egg in the incubator
I tend to see external pipping (when the chick starts to break the egg) on day 19, but it can take up to 28 days in some cases.
It’s important to heat up the incubator for 24 hours before you put eggs in to ensure the temperature is correct and stays steady.
Choosing eggs to incubate. Make sure they are fresh and fertile. You have to have a rooster to fertilize the eggs. If you don’t have a rooster you might be able to finds some through your local newspaper or Farm Supply center.
Maintain a temperature between 100°-102° with a still air incubator and 99-99.5 with a forced air incubator.
Keep your humidity between 40-50% days 1-18, then increase to 50%-60% on days 18-21.
Turn your eggs at least 3 times a day from days 1-18, then don’t turn them at all on days 18-21.
