It's hard, isn't it? You want to get in there and fuss with the incubator, rearrange eggs, check and double check the temps and humidity all the time, wonder if you can candle light-shelled eggs early.... What a bunch o' hand-wringers we are!
I have with my cell phone flashlight app. Day 4 on light cream colored bantam Cochin eggs. I'm trying so hard to behave this time around though!
