Well I think I've figured out why my previous hatches failed so badly, when I bought my incubator I thought I had bought a still air incubator so I adjusted my temps accordingly. Well today (day 6 of this hatch attempt) I was just sitting there looking at the eggs when it dawned on me, my incubator was giving off of a low humming sound. I lifted the lid and noticed the very obvious fan in the top that I had stupidly overlooked every other time I inspected it and cleaned it. My temps have been steady between 100-100.5, and I'm incubating call duck eggs. It was at 100 for the first 4 1/2 days then it bumped up to 100.5 and stayed for the last 23ish hours. Did I cook the poor babies? I'm not supposed to candle them again until tomorrow, should I check now? This really sucks! I hope I didn't kill them, what should I do
