Such a pretty chick

I have a question, my guy who hatched early AM on Day 20 is really hungry (making the hungry peeps), now it is past 24hrs since he's hatched. Can he stay in the incubator for the full 48hrs? Can he stay in longer at all? I really don't want to open it because I have 2 more pips and don't want to mess them up, but really not sure when they're going to get their butts out of the eggs.
