Oh dear, I have a Marans mix that was due today and had no internal pip but I still saw movement. The shadow didn't look right, even though it was hard to see through darker egg. I was afraid she was malpositioned. I decide to gamble and make a pip hole in the very top to check her out. Malpositioned But still alive. There was no beak visible through the membrane at all. I could see her shoulder so I knew where her wing was and where her beak should be. She still had lots of veining, but I was afraid she'd run out of air soon... I gambled again and made an incision between veins and managed not to cut any, then I took my long skinny tweezers and carefully fished around under her wing under the membrane where I thought her beak should be. I had my 265 lumen candling light in my teeth to see inside. I found it and was able to maneuver her to get her beak up to the tiny hole I'd made in the membrane. She began breathing but it looks really wet in there. Even though the rest of the eggs look fine, hers hadn't lost as much water weight and had a very small air cell. Guessing her shell was thicker and breathed less... I am hoping she won't still suffocate in spite of my best efforts. Keeping my fingers crossed for this little one. Nothing to do now but wait.... and watch. LOTS of watching....
