Late egg need help to know what to do

[crazymom101]

Son talked me into saving some ducklings from local pond where they are known to sterilize and throw eggs away. We saved 6 our first go round and one the next day. Out of the six eggs 3 ended up duds. We ended up down to three eggs with one that died. When we opened the egg the membrane was attached to the side of the ducks face. The next egg pipped and we ended up assisting because of shrink wrap, that baby is doing good. The last egg looked really weird when I checked on it. Can someone tell me if I need to help this one.
Picture of the incubator holds around 60 humidity I add water to increase it. The duckling is the surviver.

If the picture is accurate in its detail, the duckling inside has died; the membrane between the air cell and duckling is faded/not a distinct border line. I have the same incubator. Beware of the digital temperature reading. If the thermostat wire that sticks up inside touches the wet dome the reading will be way off. Make sure that little wire is straight up and never touches the dome. Otherwise it is a stable little machine as far a temperature is concerned.

Since the duckling died so close to hatching and didn't pip, I'm betting the wire did touch the dome which causes the actual interior temperature to be way above 38C. When that wire touches the wet dome the digital display is showing the dome temperature and not the interior one.

Thank you so much for the quick response. The little wire is too short to touch the side of the dome. It has about an .5 inch from the dome could this still be the problem?

The wire on mine is much longer so you have the new and improved... A half inch is fine; as long a it doesn't touch the condensed moisture on the dome. Water absorbs heat so the incubator gets hotter and hotter until the dome is the right temperature.

So disappointing, so sorry.
