Overdue Duck Eggs Day 29

[JamieMechel]

Hi! I’m incubating duck eggs. One duckling hatched 4 days ago on day 25 and on the same day another one pepped and didn’t make it out. When I was reading online, everything I was reading said give it time. In hindsight, I wish I would’ve helped. Now I have three more overdue eggs. Here’s a phot of what they look like.

You can see the air sac on the egg with the X. But no internal pipping.

If the eggs were all set at the same time and your temp/humidity are accurate, I use the general rule of thumb of 48 hours from last hatch. At that point, I candle, and/or open the egg and call the hatch if no signs of further hatching.
