Such a rewarding experience!
Basically I leave them in the Rack they were breeding in, and just take the night drop out from the Thermostat. I make sure that the clutch itself sits on a dry ground( my girls always shovel the bedding to the side before laying, so the eggs lay directly on the tub) but I leave quite a big amount of wet moss inside to keep the humidity high enough. I have never had more than about 78% humidity but that was enough. Humidity inside the coil seemed to be higher although I never measured it.
