When can you start incubating eggs after the hen starts laying?

I hope I ask this correctly. I understand that it's not good to hatch out eggs from a hen that just starts laying. I've heard to wait until the eggs are 50 gram or the usual weight for the breed of the hen.
What's your experience? How long do you wait until you hatch out eggs from a new hen?

I usually wait at least 8 weeks - but I've not incubated enough that my experience is anything more than anecdote, sorry. I just find that the rate of double yolks, "fairy" eggs, and soft shells has usually dropped to near normal after about 8-10 weeks as they bird get the kinks worked out of their plumbing.

I've hatched plenty of pullet eggs and I'd expect some may have been a pullets first egg.
I don't try to hatch any that are really small or misshapen or whatnot. I do get a lesser hatch rate from the just started laying girls but I get enough to hatch that I don't see waiting around for weeks longer.
