Omg!! I just candled at lockdown, and one of the eggs started chirping and rocking back and forth!!! My heart was racing - I've never heard a chirp at lockdown. This is the one egg that I can see through at the small end, although it's darker today than it was yesterday. I saw a couple that I thought I saw an internal pip. Never looked for it before, but it was moving. So exciting!!! 
Here's a not-so-great pic of an internal pip. The mound in the middle was moving, but not chirping. 8 eggs went into lockdown. I hope it's a good hatch!!! *fingers crossed*
I was using a Brinsea candler that shines from the bottom up. This time I used an additional flashlight to see inside the egg from the top, but clearly I need a real candler.
