Well I started out with 41 eggs and none of them made it. My daughter accidently turned up the heat at 10 days and at 14 I saw movement in most of them. However they must have died about that time because most were dead and very small. There were 2 that were still alive. After 24 days I decided to attempt to help them hatch thinking they were weak from the temp spike in their early development. I think my attempt to "help" them actually killed the only 2 that made it that far. I feel so awful. I have terrible visions of all of the dead bodies (I had to look in the shells to be sure...) It is like a horror movie! Not sure I am cut out for this at all! I was so excited to see them hatch. Is it always this difficult when they don't make it?? Why did it take the two that made it so long to develop? At 24 days the yolk was still attached.. Is it because they were Marans? someone just told me that they take longer......?? or could there have been some other problem besides the temp spike that could have caused the slow development?? maybe the temps were too low all along and my thermometer was not working?? I don't want this to ever happen again!
