heavy of course, because you do realise there's a chick in there.
Yes, a duck egg will get heavier as the chick grows inside due to the accumulation of fluids and nutrients needed for development. This increase in weight is a natural part of the incubation process and signals that the chick is developing properly.
When the egg is really hard, you know that Its been in there for a long period of time and, that its kindof heavy.
This is called candling. A very strong light is used to shine into the egg and dark spots can be seen if the egg has undergone any changes and a chick is forming.
There will be kind of pocket in the egg which contains enough oxygen for the chick to breathe in the egg for 21 days.
It is the yolk that provides the nutrients for an unhatched chick.
The son of an egg is a chick.
The chick grows in the albumen (the white of the egg) and feeds off the yolk.
They keep the egg cratled in the father's feet
I have had good luck holding the egg up to bright flashlight - if it is not fertile, the light will make the egg look transluscent. If it is fertile, the light will be blocked. Once you see it for yourself, you'll see that it's easy to do.
Depends on the type of egg. A rooster and chicken egg the thinner side is always up, because that is the head of the chick.
A chick needs a source of nutrition for it to grow in the egg, which can be gleaned from the yolk. Once the chick has absorbed the yolk into the abdomen, it uses its beak to start pecking at the inside of the egg to break it open so it can be hatched.
No Actually, studies are done every year in agricultural colleges and results are that the weight of an egg significantly decreases as the chick grows. Example: Egg weight prior to incubation 57.5 grams Weight of chick and shell on hatch 34.3 grams
