This is my second time incubating but first time with a darker eggs (Welsummer) and shipped eggs. 4/5 shipped eggs I can tell are developing well and we saw movement today. Some have slight saddle air cells but nothing too crazy. It is Day 13. The 5th one I just can't tell what's going on. It seems like the air cell goes way up one side, but maybe that's not what I'm looking at. I can see SO much less with these than I'm used to! It also seems like the embryo (certainly something at least started to develop) is maybe toward the center of the egg rather than right up against the shell making it harder to make out? Should we toss it or wait to candle again on Day 18? One side, air cell visible at bottom and embryo above. Other side...is that the air cell going all the way up the side? Or just albumen? Next side - you can see the same dark "line" as above but the egg is further turned away from camera.
