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.
