Im so happy for you! im glad all turned out well for the little guy! just a heads up once they are a week or older they can fly so make sure to have a lid on their home.
Leave it in the incubator! Check on it often, if you're lucky the chick will be strong enough to fully hatch and it will dry off in the incubator. If you take it out it will get chilled (even under a heat lamp) only take the chick out if it is too crowded (which i doubt)
