Ive been adding the paper towels in the trays of my sportsman for a long time and have had great hatches in that.I wouldnt see why that wouldnt work in the redwood.The instructions say to keep all the trays in it when hatching,even if you have eggs in only one tray.I found some felt stripping about two inches wide at the hardware store.I stapled that around the entire top of the incubator to seal it and screwed the rear cover back on.Seems to keep better temperature now with less fluctuation.I loaded up our FarmMaster 1200 yesterday with about 6 dozen eggs. No, it's not very full but I could spread out the egg types in various trays. ftw: does the paper toweling on the tray bottoms interfere with the air flow at all?We found an 18 x18 ceramic tile at Lowes to put on the water tray rails. I have a rimmed cookie sheet on top of that and ours seems to require 3 pts water every 2 days to keep the humidity above 20%. I had water in it and running for the week before setting eggs to soak the wood. The plan is to add sponges for hatching humidity top and bottom.
We threw a quilt over it too, and discovered that one area of the side at the top lid feels MUCH warmer-- like there is a leak. There is no sign of any gasketing there so we aren't sure we want to add some. No signs of air leakage at the door despite missing the bottom hinge. So far, so good. Made a turning chart so we know who pulled/pushed the slides and when. It does not seem to lose much,if anything, when we open the door to use the turning sliders.
I didn't get any new hygrometer wick ordered so we are relying on 2 battery powered hygrometer/temp displays. I don't care for the original hygrometer setup although it seems intact. Placement just seems wrong compared to all the pictures I see online.
