Firstly, you need twenty fertilized eggs.
Secondly, you need a incubator that keeps at 37.8℃.
Eventually, every day you open an egg and take the photo of embryo.
I guess at the nineteenth day the egg is going to be opened from inside by itself.

I think that is a bit much. Besides, I think it is 21 days. Here are a few links.

That may not have enough detailed info, but give it a crack.
