I have one white orpington chick in my incubator that pipped externally through the air sac 26 hours ago then rested 10 hours then spent the next 10 hours slowly making the hole bigger until 6 hours ago it could stick its head out. So its now 26 hours since pipping and its had its head out for the past 6 hours and no progress since then. It's cheaping but I wonder if it's stuck due to being pipped so long? Or how its going to unzip itself with its head now outside the egg. It's only made a hole about an inch round. In case its not dried out, I don't want to dry it out by opening the incubator which has its humidity at 67 - 70. Also, how long after pipping does the chick take to absorb the yolk sac? I don't want to lose the chick as its my only one. Do I need to give it more time or do you think I need to carefully help?
