Sorry- I'm a bit pedantic sometimes...
If the eggs are shipped ore very dark, I sand stripes.
If the eggs are medium dark, I incubate normally until confinement.
I candle both normal and sanded eggs at confinement and evaluate to determine whether they have evaporated enough mass to have a normal aircell.
If the aircell is small, I use no water during confinement.
If the aircell is normal, I use normal humidity.
If the aircell is large, I use higher humidity.
It's about not having too much moisture and potential drowning because the pigment seals the egg more than lighter eggs. You should see Penedescenca eggs try to cook- sometimes you barely get an air cell!!

If my aircells are normal and fairly large, I'll let my FBCMs go at normal 'confinement' humidity (50-80%). If the cells are small, I let them go without any augmentation at all- as low it can go. It's humid here most of the year (70+%) so I sand FBCM shells to promote evaporation if they are particularly dark or if they are shipped. I know there's an equally fervent camp that insists extra humidity is best for dark eggs, but my experience has convinced me that they evaporate poorly due to the dark coating on the eggs.
If you have the ability to hatch separately, go for it, if not, I'm usually happy hatching somewhere between 50&80% and it seems to work out. If the air cells are extremely small, you need to go dry, though, for good results.
Am I the only one that thinks this is clear as mud?
Note to self: Let a broody hatch Marans eggs.
