If they are on hatch day or after, sometimes even the smallest dip in temp can delay the hatch.. Keep your humidity up. You can use a bottle with a very fine mist, and mist 3-4 times a day or wet a paper towel (squeeze most of the water out) and wrap the egg, leaving the hole you opened exposed a bit.. Check for any progress tomorrow.. Hatching takes a lot of energy, and typically they pip the air cell, rest, pip the outer shell, rest, and then rest during and after zipping.. If there is no progress, you can very gently chip a small bit of shell off.. I prefer to use a wet paper towel over misting, because even if you take the egg out, it will still be wrapped in moisture... If you see ANY blood at all, stop and put it back in the incubator..
Even helping (which is a touchy subject for some), can be a lengthy process.. One of 3 things are happening.. 1. It's resting and there should be progress by tomorrow.. 2. It's shrink wrapped, and can't move, and you will have to step in the help slowly.. 3. The gosling has a deformity or is in a bad position in the egg, and cannot hatch properly.. In the third case, prepare yourself in case you need to cull it after it hatches.. One other thing.. If you need to help, be very careful as the yolk may still be absorbing.. If it is not absorbed, other gosling or even dragging it on the incubator floor can pull the little ones intestines out...
Keep me updated on how the little one does!
