4H, please don't take this wrong as this is only out of concern and to help you and the chicks: after you spray the incubator, CLOSE IT and KEEP IT CLOSED until the chicks hatch. The pictures you are posting are great, but opening the incubator severly dries out the membranes inside the eggs which causes the chicks to stick to them and makes it much harder for them to hatch.
I didn't think opening the incubator would affect the chicks that were still pipping, but I found out the hard way with my recent first hatch- the first four chicks hatched out fine, but then I opened the incubator and it ended up drying out the other two that were still pipping, even though my humidity was over 70% the whole time. I had to assist their hatch, and when I finally got them out, it was like they were covered with super glue; I'm not exaggerating. They are doing okay; but not nearly as good as the chicks that hatched without assistance. One still has membrane stuck to its wing.
