I am late joining this thread, and I didn't read all 8 pages, but I remember soooooo well the excitement of that first hatch (and every hatch since then). Good luck!!! And I am praying for you.
A couple of things - someone else may already have told you, but just in case they haven't - Don't be in a hurry to try to help a chick hatch. Some come out really quick and some take hours to hatch. They need to work at it in order to be strong enough to survive. Also, the effort causes them to absorb the yolk sac. This is very important. It gets so tempting to help them, but don't.
Also, try not to open your incubator any more than absolutely necessary. The changing temperatures can affect the unhatched eggs.
I sooooo hope you have what I call "beginner's luck" and your hatch goes exceedingly well. There is so much that can go wrong with an incubator hatch, but nothing is more exciting than that first chick. Keep us posted on how it's going.
