Some people (e.g. on nano-reef) have success with pulling eggs very early, even day 1. That requires a lot of aeration on eggs later - and some experimentation to master technique. I think it is discussed in detail in NR Breeder`s lounge.
It can be done but not all eggs will survive. Trust me, been there and done it many times.
The reason that they pull their eggs early because parents keep eating all the eggs. I always pull my eggs out on the 7 day and have lots of survive.
