when does the chick start to develope?

when an fertilized egg is laid when will it start to develop? When the egg is laid or once the hen starts to set?

 

[Yorkshire Coop]

It will begin to develop when the hen starts to set or the egg is placed in an incubator at the optimum temperature.

 

[Antcohan]

It will only start to develop when a hen starts to set or put in an incubator at the right temps.

That is what I thought
