First you drag the big duck away from its original spot, then click the smaller duck. Hope I helped.
A duck egg that has died will no longer have any movement or development inside when candled. It may also emit a foul smell when cracked open. If you suspect that a duck egg has died, it's best to remove it from the incubator to prevent potential contamination of other eggs.
A fertile duck egg will typically have a distinct bullseye-shaped spot on the yolk when candled around 7-10 days after incubation. This spot indicates that the egg has been fertilized by a drake and is developing an embryo.
These are called blood spots and can appear in either the white (albumen) or the yolk. This happens when a small blood vessel breaks in the birds oviduct and deposits a trace amount of blood onto the forming egg prior to the formation of the shell. This tiny spot of blood is not harmful and will disappear when cooking the egg. Most restaurants and home cooks remove this blood spot simply because it is unpleasing to look at but it will not harm you.
The tried and true method is to hold the egg up in front of a bright light; a chick inside would appear as a dark spot inside the egg. Otherwise, by looking at it, you cannot tell. If you weighed it over time, the egg would become lighter if a chick were developing inside it.
The dark spot in the nucleus is called the nucleolus

The Great Dark Spot on Neptune, similar to Jupiter's Great Red Spot, is a massive storm system on the planet's surface. It is estimated to be about the size of Earth. Therefore, you could fit approximately one Earth inside Neptune's dark spot.

After about 2 days shine a torch or a candle light in a dark room above the egg, if you see a red spot it is likely alive, after 11 days do the same thing and there should be viens that you should be able to see.

Yes it does. The spot is called 'The Great Dark Spot'
I believe that would be the nucleolus.
