I have 15 call duck eggs under my B.O. today is day 26 ,I have 3 internal pips one nearly 20 hours now when should I make a hole in the shell ??????? I have read so much about how hard they are to hatch that I am terrified they will die in the shell all 15 are alive,I only read today that I should have misted them everyday ,I misted them this morning to try and keep the humidity up but it is very hard to keep checking them when they are under a broody chicken .Any advice out there ???????
