I'll just add... I use a bigger lay box with moist coco-fibre, checking for eggs frequently if I expect a female to lay (add some water to the coco-fibre so it's moist, & squeeze out the water so it's not too wet).
I also open my egg containers during incubation and wipe off the condensation from the lid/mist the container lightly to replace the moisture.This keeps the condensation from dripping back down onto the eggs and causing mold.
& what I've found works for temp sexing is 79-82 degrees for female, 83-86 for a mix M/F, & 87-90 for male.
