One of your duck egg accidentally got bumped and cracked on the air cell end day 19 incubation you were wondering if embryo could survive with a little dent shell?

It is possible for the embryo to survive, but it will depend on the severity of the dent. A small dent may not affect the embryo at all, while a large dent may cause the embryo to die.

Here are a few things to keep in mind:

- The air cell is located at the top of the egg and is essential for the embryo's breathing. If the dent is near the air cell, it could block the embryo's access to oxygen and cause it to die.

-The dent may also cause the egg to leak, which could lead to infection and ultimately the death of the embryo.

-If you are concerned that the dent may have affected the embryo, you can try candling the egg to see if the embryo is still alive.

-If the embryo is still alive, you can try to repair the shell using a piece of scotch tape or clear nail polish.

-It is important to note that even if the embryo survives, the dent may affect the quality of the duckling.

-For example, the duckling may have a crooked beak or a misshapen head.

If you are unsure about whether or not to hatch a cracked egg, you can always contact a veterinarian or poultry expert for advice.
