Died in shell

[PhlyinPheBee]

What does it mean when you have chicks that make it the 3 weeks, are fully formed and never make it out of the shell?? I do not understand this. I have a friend that now has done 2 hatches and some of the ones that did not hatch were perfect chicks!

It just happens. Could be they are laying wrong in the egg or just that they were too weak to break a hole.
It happens almost everytime when i hatch eggs that 1 or 2 wont make it out.
It´s nothing to worry about as long as it´s not alot of the chicks that dies.

Too high of humidity and the air cell will be too small to supply air during internal pip.

Too low temps during incubation and you will have improper embryo development..too weak to hatch.

Too high of temps in the hatcher and the chick will not be able to absorb their yolk to complete hatch.

Malformation or malposition of chick (head under wrong wing) and chick is unable to pip.

Poor breeder stock, poor nutrition of breeders, etc.

Old eggs - but these usually end up blood rings versus grown chicks that don't hatch.

Lethal genes can also cause dead in shell chicks.
