Aww

. do you have a second thermometer to go by? What kind of incubator do you have? I agree with chiqita on calibrating. My first incubator (at 12) what a still air hova bator. got great hatches, and was around a long time. I never measured humidity just filled up the trays like the directions said. But with cheap eggs, things seem easier. That's how it always its though.
I would get your incubator set up now and check the temps. Did you put the eggs in a bag, open them and see where they were at in development. I should have done that before myself, but too grossed out at the time.
What are you trying to hatch? Any breed in particular? I have some babies coming up in a few weeks. I don't ship though. If you're interested you can have your mom message me and give me a call when they hatch. I have marans and the marans/lav AM crosses seem to be doing well. I'm actually excited about the crosses. Hoping they'll be some pretty OE. I can give you some if you'd like. I don't want to "count them before they hatch" though. Just don't' know how to get them to you if you're interested.
