The info I was refering to on temperature is in this article
Quote:[FONT=Helvetica, Arial, sans-serif]This is plain and simple, yet the MOST important part of hatching.[/FONT]
[FONT=Helvetica, Arial, sans-serif]Still-air incubator (no fan):101.5 degrees measured at the TOP of the eggs.
Fan Forced incubator: 99.5 degrees measured anywhere in the incubator.
Humidity: 60-65% for the first 18 days, 80-85% for the last 3 days.
You can sneak by with humidity numbers that aren't very accurate, but the combination of poor humidity and temperature will definately cause problems at hatch time. If your temperature is not accurate you will DEFINATELY have problems at hatch time. The bigger the deviation from the proper temperature, the bigger your problems will be![/FONT]
I used this info when I first started hatching. I personally have less problems with eggs if the temps are on the low side of the range. I actually just had an incubator get unplugged for 2 days at day 17 and still had 6 out of 25 hatch after I plugged it back in. I think its just like a chick that gets too cold, you can sometimes see them come back when they warm up. Once their cooked their done though. I hope you get it worked out. One of the most frustrating things in the world of chickens that loosing chickies

Congrats on the new baby alpaca! That must be fantastic!!!
I don't agree with those humidity levels. 80-80% you risk drowning them. I add water for the day I set my eggs (which brings it to roughly 35%), then don't add any water after that til lock down. At lock down, I add water and bring it to 55-60%. Everything that is viable hatches. I don't have any glued chicks or any other hatching issues. My last hatch had 16 eggs going into lockdown, and 13 hatched. (the 3 that didn't were late quitters)
IMO temperature is far more important. I recommend the Brinsea Spot check thermometer as it's accurate to .1 degree.
If the window is fogging up, your humidity is too high.
