Yesterday I went to check the temp on the incubator. It was 120 degrees. I'm not sure how long they were at that temp, but anything over 101 will kill the embryo. We let them go until tonight and then first candled them (and saw nothing) and then cracked two open.
This is what we found.
This is what we should have found.
So, we reloaded the incubator with a fresh batch of eggs and we will watch the temp a bit more closely.
