Duck eggs? Are they growing?

[obieandhisgirls]

Did you try cracking them open to see if they're fertile? May way to keep eggs handy at this time for eating, you don't want to keep throwing infertile ones in the incubator.

Crack a new one open and take a pic...

i took one of them out of the incubator and cracked it and nothing was there so I took the rest and all of them were just yolk nothing in there. I have one left that is growing out of 16 here is a picture of one of my eggs and I think the reason they all did not grow is because one night it went up to 40 Celsius and I don’t think I got to them in time and that was on he second day
