    Hi All

    Been reading for a while and just pushed to finally post by my emergency here in freezing Scotland.

    First hatch of some mixed Campbell duck eggs. I got home around 1830 this evening to find the power out since about 1600, the temp inside the incubator was around 10c - 50f and will have dropped fairly quickly when the power went off as we stay in an unheated caravan and its freezing outside.

    I put the eggs on my belly and basically sat there for the past 5 hours keeping them warm with a tepid 38c 104f hot water bottle in a towel and my own body heat. When the power finally went back on I brought the incubator back up to temp and then candled them and put back in. Of the original 3 that looked pretty good with big air sacs I saw movement in them all....hurrah! Is that unusual or would you always expect them to survive a 3 hour drop of temp down to 50f with a nice slow return up to around 100f?

    They went in saturday 4 weeks ago about noon so are about 12 hours away from being exactly 28 days in the incubator...

    So is there anything else I should do now and how long can I expect to wait before they get though the shell? I expect they may be a little weak? But then they did survive being on my belly though several sneezes coughs and eating dinner so hopefully not too weak...

    Anybody with any advice do please let me have it.

    Many thanks
    H

    Hello, H, and welcome to BYC. They should be fine although hatching may be set back a bit. Eggs, especially in the last part of incubation, can handle occasional chilling quite well. Excessive heat is far more likely to cause mortality. Good luck for a successful hatch.

    Hi

    Thanks for your response

    1 egg seems to be alive still - its 36 hours past hatch date and it have managed to push a little bump onto the surface of the egg with a few little cracks around it. That was about 6 hours ago, the bump doesn't seem to have changed shape att all since then and the slight movement of the egg seems less frequent than before - is there anything to do to help it out or should I leave it? Can candling them harm them at this stage?

    In my experience ducklings take their sweet time to hatch. They can take up to 24 hours plus from external pip (through the shell) to progressing. Make sure you keep the humidity in the incubator 65% or more, so the little one won't dry out in there and fingers crossed all will go well!

    Hi thanks for the response

    I guess the one that has externally pipped will hopefully be ok...

    Will I harm the others by candling at this stage? My incubator is easy to get into without humidity or temp loss for more then a minute or two and it would be good to know whats going on in there - but i dont want to harm them..

    we are 36 hours past a full 28 days now as in your linked post might this be the time to get involved with the two that haven't pipped - assuming they are stil alive?

    thanks
