Ok I have 6 eggs in my incubator that are due Saturday however when I put them on lockdown 2 of them had their beaks into the aircells already. The other 4 I couldnt see much, too dark which I am assuming is a good sign? One of them, a pekin, pipped last night and fully hatched about noon today, 2 days early. I still have 3 welsh harlequin eggs and 2 runner eggs and no other pips, I have never successfully hatched ducks before, just quail, should I be concerned or is this normal? How long can the pekin be in there before I have to open it and get her out?
