I have 8 duck eggs under my broody goose. Today was day 7 so I candled them to see what was going on. 1 was not developed at all ( I started with 9) the others all have veins. My concern is that rather then the veins and everything being in the middle they are off on the side in most of the eggs. What caused this? I think maybe the goose is not turning them herself and its causing them to settle to one side? Are they going to hatch ok?
