We are on day 23. Last night about 12 hours ago I candled/floated the remaining eggs in the incubator. One egg was chirping so I didn't float it. I could see it with the light that it had pipped internally. Another one I floated because I did not hear sound and did not see movement. It bobbed slightly, I waited to see that I was not hallucinating and the other eggs stopped, this one was bobbing. I put these two eggs back into the incubator. I am worried now about assisting the hatch. I read the document at least 20 times now. Last night I lost a chick that hatched with a yolk sack and I am still stressed over this batch. If there is a chance I want to have these last 2 hatch. There were 8 eggs at lock down. 3 hatched on day 21. One hatched on day 22 with yolk, it died after 20 hours. 2 eggs were malpositioned and died (one with the head in the small end, the other had the head on top of the right wing). So 6 eggs are done, 2 more left in the incubator. I am not sure when the internal pip happened, but I heard it 12 hours ago. Should I still wait until it is 24 hours? Or is it time to check if it is still chirping, given that it is day 23 already and I don't know how long it was already pipped. I was involved with the one premature chicken and I had to open the incubator from time to time. Temp is still 99-100, humidity is 60-70%. I am constantly monitoring and feels like I am standing there all day watching but nothing is happening.
