I've never hatched in winter before. Very dry in house (AND we have a fireplace)! Having trouble keeping humidity up. Next Tuesday is lockdown. I've noticed some of you put a sponge in a dish in bator. Is the sponge damp, wet, or damp with water in dish? I try to get humidity to 70% but it's gonna be hard cause I gotta go to work. Got 37 live one & don't wanna lose any (who does?) Thanx!
