My Duck Eggs Are Perfect Ovals!! Which is the Small End?

[swampducks]

My "broody" rouen duck is only a day time setter, she sat for a little while yesterday, today she sat all day and tonight she left for the pond, covered them all up nicely with leaves but what good does that do? Then we had torrential rain. They were very wet.

DH fixed the incubator (yay, DH!) when he got home so at 11 tonight I brought the eggs in.

All 12 have no pointy/small end. I am having trouble finding info on how else to tell which end down so I guessed. I candled and there's this dark circle on one end of each egg. I am guessing it's the air sac? So I put that end up.

Am I wrong? Please let me know.

i thought my rouen girls were the ONLY ones who did that!

Honestly the only way I can tell for sure on some of them is incubation. I had one egg who I just discovered after 10 days was incubated upside down and is still doing great

I saw where someone recently recommended laying them on their sides until you can tell when candling. That way there is no danger of turning the wrong side up.
