It’s good youot some beautiful babies. Most look to be the same coloration? I wonder if those were just healthier more robust genes.I had to rethink the eggs that didn't start. I don't know if that's a fertility thing or that the eggs were just that badly scrambled by postal service that they were unable to start. I think there's no way of knowing, but the evidence is in the air cells, for sure. I had some cells that were just a mess.
To my surprise, however, despite incubating my eggs on their sides, some of those more misshapen air cells corrected significantly by lockdown, and very surprising is that the small-end-of-egg-cell hatched a healthy little baby. That said, the smallest egg is one of the early deaths, and the worst saddled air cell was also an early death. My late term babies both had acceptable cell shape and position and still ended up dying for some reason.
What are you hatching? How many eggs? What day are they on? Are they shipped, too?
I’m hatching some mixed bantams from a local backyard chicken keeper, so aircells were thankfully not an issue.
There was a heat wave on the days the eggs were collected, and I should have asked for eggs that were laid after the heat wave was over. But I was anxious to get underway with the incubation and wanted to trust the seller to know what she was doing.
Lesson learned I guess

4 were definitely unfertilized as I opened them on day 7. None of them showed a hint of development and there were no bullseyes. I couldn’t bring myself to open the early death embryo...
I just hope I don’t end up with just one chick. I really don’t want to go out and buy 6 chicks (state minimum) to keep one company
