So, I started my fourth hatch last Wednesday. Candled today (Day 7) and not a vein in site. My first hatch was only three eggs--one grew and I knocked it out of the incubator and killed it on like day 14. Second hatch were all duds. Third hatch started with 14 eggs, 7 developed and none hatched. Two were fully formed and at least one tried to pip, but I think I had a humidity problem. This batch is from hinkjc, so I feel pretty confident in their fertility. It has to be something I'm doing or something with my setup. I've struggled with keeping my humidity up--it likes to sit around 30-40%. I've got three thermometers in there which all read between 99-101. The incubator is a little giant still air. I was going to attach a fan but couldn't find one that would fit before these eggs arrived. Should I get a clue and just give up? I feel like I'm banging my head against the wall.
