When should I take the chicks out of the incubator?

[EmmieLou]

So I have 29 eggs I am trying to hatch. The problem is that they are all different ages. some started the 31 the 1 and the 2. So when the 31 are done should I take them out? Even thought the other ones will still be hatching??

It's best to not open the incubator until they're all done. They can stay in there a couple days after they hatch.
Hopefully the ones set on the second won't be late.
If you do have to open before they're all done be ready to spritz the eggs with some warm water.
