. Yea too cool I thought you were allready hatching dry at least partially dry 30-35% during incubation seems to be about perfect for most breeds I have only had issues with over evaporation one time in the last few years and that was due to it being in the height of the dry season here and my ambient humidity being to low I corrected it with addition of moisture to the bator and still had a good hatch but the following set I used a single burner hot plate and a tea kettle to bring up the room humidity and all settled down my bator room is a converted walk in closet ( the wife was happy about that one ) so controlong the conditions are easy for me ,,,, shoot me some pics of that new batorDid you watch the video? You can see the air cells lines on my shells...lol That is from 7 days, 14 days, then 18 days. Humidity ran as high as 31 and as low as 21. I am taking notes with this last bunch. The Cream legbars, ameracaunas and silkies. Pretty sure this guys head roo a RIR is infertile. This chick and the one I can see are both dark. His other roo is a barred rock. First batch of 35 eggs only 12 were fertile. Second batch of 24 only 12 were fertile.
