You can collect eggs for one week, keeping them in a cool place until you are ready to put them in your incubator. Store the eggs with the small end pointed downward. Do not store them in the fridge!
If you are using an automatic turner is to remember to turn it off and remove the turner when you need to stop turning the eggs when you lock down your incubator.
You are going to lockdown your incubator three days before they are due to hatch. Meaning, you are going to stop turning them, and you are going to stop opening the incubator.
