I can concur. I was going to be good and wait for at least 2 months after my girls started laying but things happened and I had a need to incubate sooner than later. I did set and hatch several first silkie eggs. I had a decent hatch rate and the chicks are now 20 weeks old and all are doing great.
There are still many reasons to wait. Wait for the eggs to get a little bigger, wait to be sure they have the traits you want to reproduce (character / health / egg laying rate etc).
My intention is to only incubate hen eggs in the future, but sometimes life throws you curve balls and you have to do what you gotta do
