Hi there. This is my first incubation. It is day 20 and one egg when candled looks bad. These are Cambell Ducks. This egg was developing fine when candled on day 10, but by 18 it was different. The darkness is more of a splodge with small splodges near by. It only fills half of the egg. No movement. I would like another opinion before I discard the egg please, just to be certain. Thank you.
