I have a duck that is on her second nest. First nest she laid 24 eggs none of them hatched. She then abandon the nest. After a week after she abandoned and not going back to next I disposed of eggs. I cracked then none of then had any embryos. Here my question she's on her second batch of eggs this time 21 eggs she's been sitting on then until yesterday. She has not sat on nest since yesterday but she does come back to nest and sits right next to it and it's sometimes touching 1 or 2 eggs by how close she sits to nest. What does this mean? Are they close to hatching?
