Eggs 4, 5, 6, 7, 9 and 10 have pipped so far. I think egg 6 is zipping. I write on the glass the times they pip and zip, I hope you can read it on the glass.
Day 28. Hatching day.
7 ducklings hatched, 4 with good colour. The 8th egg didn't pip. It was still rocking and chirping this morning. I kept an eye on it till now. I couldn't hear anything in the egg so I pipped it, and after getting on response I zipped it and popped the top off. We lost it. If I had grabbed it this morning it would be alive. Today is hatching day!
From now on I'm ignoring hatching day, once the last egg hatches, I'm going in and starting the last one off.
I'll put more vids and photo's later.
Thoughts:
All of the 7 eggs took no longer than 22 hours from pip to zip/hatch. I should have pipped remaining eggs (just 1 left) about 22 hours before hatching day, today. I should of pipped and zipped, letting the head pop out. It would have been weak, but alive.
