I've never ate wild ducks eggs before so I can't answer that question . and as far as all eggs being fertile or not being I really can't answer that one either, but i can tell you that my domesticated ducks are not mating right now and i imagine in the wild they aren't either so I think you can probably assume they aren't fertile, but we do eat fertile eggs when my ducks are laying. honestly you cannot tell any difference at all. It's not a duckling till mama begins sitting and they start to develop.Thank you for this.
Are wild ducks eggs good to eat (is there any difference between those and domestic ducks)?
Also, is it safe to assume that if one egg is/is not fertilized that the rest of the batch will / will not be too?
