What to do after eggs hatch

Hello, I am expecting my first clutch to hatch in the next 2 weeks. I've researched what to do once they hatch and read that you should keep them together in a container with damp paper towels in the incubator. What kind of ventilation do I need in these containers after they hatch? Do I need to drill/melt some holes into the container?
Thanks!!

Once they hatch and fully emerge, put them in a tub on damp paper towel in your rack, there is no reason for them to be in the incubator at that point.

And yes, of course, they need air holes...
