Hello, I'm new at this please bear with me. I have a duckling who should have hatched before now. We are on day 30 and the others have hatched. This one had pipped internally we helped it along last night just a little bit since it had been almost two days. They have all struggled with hatching I'm wondering if I went wrong somewhere and maybe the eggs cool down and that's why I'm having such a late hatch? But this one chick seems to be shrink-wrapped and so I'm using wet water and a Q-tip to keep her membrane from drying and it's not helping much. I started to assist again this morning but as I go further it almost looks like there's still some yolk left like she hasn't absorbed at all there are still a little bit of rounded vain. I will see if I can figure out how to attach a picture. But I'm worried about the shrink wrapping! I really don't know what to do!
