Hi, I have read that ducks do not move their eggs. I have a duck house that they have not left for several days due to the weather. I am certain there are no predators that could access the nest. I have candled my eggs that are very close to hatching. I candled them two days ago and there were three ready to hatch in this one nest. I have two nests with eggs developing by two mothers. I went in the next day and there were then four, which were all close to hatching. I then went in today and there was only one egg in this nest and the other three were moved into a new nest, which a third female was laying on. I now have three nests and they keep moving their eggs. Is it possible they are eating their own eggs? Will they eat the ducklings? I am confused on what is happening?
