Borrowed a friend's incubator and set it up at my daughter's preschool...which is in the teacher's house. Got two fertile eggs (don't need that many more chickens right now) and put them in. Candled them after a week, definitely had development. Due to hatch the end of this week, candled them again to make sure all was well and I think they stopped developing sometime I'm guessing last week. There is too much space for light to shine through, not a big enough dark area suggesting a chick. I know they were turned right, the temp stayed steady right around 100, humidity should have been fine the incubator was just used recently to hatch other eggs. Now the kids are bummed, I'm bummed, the teacher feels guilty even though I've reassured her that it wasn't anything she did or didn't do. I knew there was a risk of this, especially with only having two eggs in there but for both of them to be gone really stinks! Anyone in NE PA willing to let me buy a couple eggs? We would like to try again....but maybe we shouldn't.
