In my last hatch I had 2 pip on the pointy end and on the bottom. I wondered why there was 2 that hadnt pipped and half of them were already out, it just so happened that 1 of the hatched ducklings fell over the eggs and turned them and I saw the pips with goo like stuff. I took the bator down to the bathroom, turned on the shower to get the humidity up and took a load of the shell off each egg. They were ready to hatch, no veins and both were out in half an hour, they had zipped all the way round and couldnt get out on their own. They all lived and I sold the last 9 today all healthy and happy
