I have 3 Serama eggs in my 'bator-2 had tiny holes they had pipped out at 8 this am. Today is day 19-so right on schedule but......They haven't made much progress and it is 10:30 pm now. How long do they take to hatch? At what point do you intervene? This is my first incubator birthing episode and I'm about to stroke out. I'll have to call an ambulance for me at this rate! ANY advice is appreciated!
