first eggs from any bird can or cannot be fertile, but as mum stated fertile or not as long as you collect daily and dont incubate them they can be eaten just any egg you buy at the store. All of our eggs are fertile that we sell out of each and every week to customers for eating. Just dont tell the kids when making breakfast. You dont want to turn around and incubate every single egg if you dont have room for the ducklings or buyers for them as that is not responsible ownership of the adults. As Lydia stated though dogs LOVE eggs and we too feed eggs to our dogs.
