It's day 5 for my first attempt at incubating eggs. I candled today. All of my eggs are developing! However, all of the eggs look like they're around day 4, with veining but still showing that vein-y circle. One egg though has veins that look like a typical day 6 or so I would say, with a visible eye spot. I'm using a DIY incubator that I think is actually doing pretty well. I set it up three weeks ago and worked on regulating the temps where they should be and making sure my thermometer worked right and such. But the first day I set the eggs into the incubator I had fluctuations. The eggs never got too hot that first day, but they took a while to get up to temp, sitting around 85 I remember for a good part of the day that day. Other than that, I've been opening up the incubator to turn eggs three times daily and the temp will fall to 95-99 or so and come back up after an hour I close it back up. Are these temps causing this development to differ so much? Will it harm my hatch? Thank you for the help!
