Day 21 starts in 5 hours. I had one egg pip yesterday, but at the wrong end. It is one of those eggs that have almost equal ends, but I can tell this is the small end. I don't know if the air sac is at that end, because I didn't mark the end when I candled. There was a small spot of blood on the membrane where the chick pipped, but that has since turned old blood brown, so no active bleeding. The chick is alive and peeping, but hasn't started to zip yet. Will this chick need help? Should I candle now and see where the air sac is, or is that no longer an issue since the chick can get outside air? Humidity is 68%. Temp is 99.3-99.7.
