I have 2 breeds in the incubator in two trays. RIR and Marans. All the RIR have hacthed and only a few pips in the Marans. The RIR's have been hatched about 16 hours. I was getting worried about them. All eggs were set the same day. It's day 21.
I'm not an expert here, but from everything I have read on this website, they are ok for three days after they hatch without food or water. Opening the bator to remove the hatched chicks will drop the humidity and potentially reduce the hatch rate of the eggs that have not hatched yet.
Post #2 is correct. They will be fine for up to 3 days. I usually leave my chicks in until they are all hatched, dry, & fluffy. It's a good idea not to open the incubator until all the chicks are hatched.
