(Candling
hold the egg up to a light and look through it, if it is fertile there will be a dark spot.)
No, sorry, although the above answer seems to be on more than one copy of this question, it's wrong. You can't tell if an egg is fertile that way unless it has been incubated. If incubated, you will probably see red veins first. Incubated duck eggs are very active inside. You should see some movement in the embryo. At the earliest, I tend to think I'm seeing a beating heart, but it might be something else moving around. If all you are seeing is a dark spot with no happy veining or movement, that's not a good sign. Most of the time that's either a dead embryo or a bit of rot. You might want to look up some egg candling info. 10 days into incubation is usually the earliest I check, but I have peaked earlier now and again.
If you haven't been incubating the egg, the only way to tell if it is fertile is to crack it open. One side will have a white spot. If the wrong side is up, carefully turn the yolk with a spoon. If the white spot looks more like a bulls-eye, the egg is fertile. If it is just a single white spot with no ring around it, it is infertile. Of course, at that point, you'll be making an omelet instead of hatching ducklings.

∙ 13y agoIf your duck is sitting on her eggs, you won't know until the fertilized ones hatch. Maybe she knows? But if you are hatching eggs in an incubator you should do a process called candleing 7 days after they start being incubated. and again 7 days after that. This is where you have a box with a hole in the top to hold the egg still, and a light bulb underneath so you can shine light through the egg. (done in a fairly dark room helps) If you see veins, or a little dark spot beating, you have a fertile egg. If it is clear, it is not fertile and you need to get rid of this egg... throw it away, do not eat it.

∙ 12y agoYou can see them pipping the outer shell and even before that when they are pipping the inner membrane (if your incubator is in a quiet room) you can hear the ducklings cheeping inside their eggs
