I have 17 eggs in the incubator. Yesterday was day 21, out of 17 eggs we put in only 2 hatched yesterday morning/afternoon. Since those 2 the other eggs have not even started pipping. Should I be worried no other eggs have started hatching? Should I leave the baby chicks in there until they do or should I take them out? I’m sorry I’m new to this and I have never had chicks not hatch all at the same time or around the same time. Thank you for all help!
