The bullseye is there immediately after the egg is form and in the shell. Even a freshly laid egg will show the blastoderm. However, it takes a trained eye to know if it is truly fertile or not. There is still a spot on the egg called the blastodisc or germinal disc, which is the site of the growth of the embryo when it is fertilized, then develops into the blastocyst, then eventually into the embryo once it is incubated. Most of us with roosters running with our hens have been eating fertilized eggs since the day the rooster came along and the first egg was laid. It doesn't hurt a thing and you aren't eating an embryo because nothing is growing, especially if you collect eggs daily and refrigerate them. It takes a constant temp of 100-degrees for over 24-hours (I don't know off hand exactly how many hours until the cells begin to divide to create an blastocyst) before the actual growth begins. Even if you leave a fertile egg on the shelf, or in the garage as I do, for 10 days, nothing is growing until that heat is added and for long enough to trigger development.
Is he afraid he is going to be eating 'tadpoles'. Do we need to start making bumper stickers and t-shirts that say, "Real men eat fertilized eggs and love them!" ? LOL!

If a mallard starts laying in the winter, do you think she will continue till spring? I know mallards aren't known for egg production, so I was surprised when she laid.
Yes, the bigger the duck, the bigger the egg. Bantam ducks lay smaller eggs that the light chickens, light chickens lay the equivalent of medium to large eggs, Medium ducks lay the equivalent to a large to extra large chicken egg, and heavy ducks lay jumbo eggs. Even when they start out laying, Pekin ducks lay huge eggs compared to chickens.
I wouldn't bank on the mallard laying all winter. I would guess about the end of December you won't be seeing any duck eggs, unless yours are some super special super egg laying strain that winter doesn't effect. I know I like having ducks at this time of year because when all the chickens stopped laying, the ducks would pick up the slack. I think duck egg shells are so cool too!
