I have 2 that piped and didnt do anything for several hours. I was worried so I opened them up and one all the way. He looks really underdeveloped and just lays with his head in the same bent back spot as if he was still in the egg. It has been out for 4+ hours and is still breathing and occasionally peeping. It has also moved a little. I am just concerned as it looks underdeveloped. Its body looks like a hard boiled yoke. The other I left inside the egg but did open it up a little when I opened the first. Questions: Why would they be underdeveloped? I have removed 6 from this batch to the brooder already. All of them hatched by themselves. Should I have intervened? I have heard if they dont hatch on themselves they most likely would not live any ways. What if the humidity dropped to low and dried the membrane out to much? Wouldnt that be time to intervene? Should I leave the second or open it up all the ways like the first? How many days should I give all the others before unpluging?
