Has anyone noticed the paper egg cartons effecting the humidity in any way? Do they suck up more moisture so it needs to be higher or do you think that evens out very early on? My eggs have arrived!!! I have an egg carton lid in my incubator now (it was running without egg cartons for the last 24 hours). I'll set the eggs tomorrow but wondered if anyone had info on this. I'd like to use the cartons for the first 18 days, assuming they will fit in the Brinsea 20.
