I put foil over most of the (one) original plastic water tub in my GQF 1266 for the first part, vents wide open, as described in the Dry Hatch Method posting on BYC. I do let it go completely dry before I fill it up as recommended. At lockdown I have to put a big 13" X 9" baking pan in with a huge kitchen sponge on end for more surface area and close up the two large vents to get it to 65%. I always keep the ventilation holes open (the smaller ones, two on top and two on bottom in the back). We have a wood pellet stove for heat with an open teakettle on it to help keep the room humidity up a bit and there is also a 45 gallon fish tank with an aquaponics tub on top of it. The room temp and humidity have a LOT to do with what goes on in the incubator I have found. Can you all visualize my living room now?
When you say dry hatch Ihilani... do you even check a hygrometer? They call it relative humidity. I can see why. I am bouncing it between 20 and 40 in the incubator and I am holding 68 in the hatcher. With the little vents open. I think alot of this depends on where you live. Today one of the three that were due has pipped a hole in the shell and is sitting there for nigh on 24 hours. He looks alright. and I am not touching him. The eggs are definitely lighter as I moved them to the hatcher last night and the ones I weighed previously were right on to hit 13% I think in my environment, a little on the dry side is better.
