Bummer that you lost a hen. What day of incubation were you at when the low temp alarm went off?

We have a NurtureRight 360 and it has been rock solid at 99.5. I had two occasions where it ran out of water overnight and the humidity dropped to 5.

I added a cheap digital thermometer inside when I took out the egg turner. The digital thermometer registered 96.5 degrees. I read that 95 degrees can cause disproportionate development, resulting in chick die off. So, now I am second guessing my temp control. I am thinking about bumping the NurtureRight up by 1.5 degrees just to be sure.

Yesterday was day 18. I have 12 eggs unhatched as of this morning. I?m going to let them go until tomorrow afternoon, just in case I can get a couple more late bloomers.

As it is, I had a 20% hatch rate with eggs shipped in January from the east coast. I guess that isn?t too bad, considering.
