Nervous

It's Day 21 and my chicken eggs aren't doing anything.  I keep peeking in at them through the windows hoping one of them has started pecking through the shell, but nothing.  I'm nervous and sad that none of them made it.  Which would be a big, huge bummer.  Ugh.  I really feel like I did everything right.  Unless my thermometer was off a bit.  I just used the one that came with the incubator.  I don't know.  Some people said they may not start hatching till Day 23 so, I'll wait a few more days and hope that at least one little chick made it.
