Checked the eggs tonight after I got home from work. Looks like 16 of the 36 (I noticed one was cracked) remaining are totally black inside when candled from the pointy end, meaning a developed chick!

A few others show either entirely clear, or some sort of mass inside of the clear. I'll wait a few days past hatching to see what they are going to turn out like before I perform an "eggtopsy".

I'll pull them out of the racks Wednesday, which will be day 19, and pile the good eggs in the center of the incubator as instructed, and pile the questionable ones around them.
