(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.
If 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.
You 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
theyre all shaky and start cracking
No if you touch duck eggs or alert the duck to the fact you know where her best is she may leave and or abandon the eggs
Duck eggs are formed inside the female and fertilized inside the uterus. The eggs are then laid by the duck via a vaginal canal through an orifice called the vent.
The duck does take care of the eggs for the most part but there have been times when the drake will sit on the eggs as well to give the duck a break to go feed.
Welll... a female duck only lays 3-8 eggs in its lifetime, but a snake can eggs whenevr it wants
I have no idea and why would you want to know that?
No
12 days
No. If the female attempted to hatch eggs without a male, the eggs won't be fertile, and the egg will just go rotten.
No, a male must fertilize the eggs or they will not hatch.
there are ducks in place of the eggs
They quack
Fertile eggs

As with chicken eggs, fertilization occurs prior to laying the egg. It takes a week after mating for a duck's eggs to be fertile.
Yes, and you can eat them too! They taste very good. The only time when they are fertile is when the males are around. Usually in the winter/spring. ,Alice Do duck eggs taste like chicken eggs?
Most duck eggs are larger than a chicken egg. PoultryTalk's Response: Smell the egg, duck eggs have a scent chicken eggs dont. Also most are glossy and sometimes they are a greenish color. Also duck eggs are usually thicker.
