Yay!! So excited for you!! I had two pip the wrong end and side in my last hatch. One hatched all my himself and the other I had to help. I waited 24 + hours and slowly started to make a zip. Are their beaks sticking out? Just keep in mind that a wrong end pip is not only the external pip but also the internal pip, so they can take a bit longer. Mine was yellowish and bloody when they pipped the wrong end. What's your humidity? Can you get a pic?
As for the other egg, did the air cell draw down? You can't kill an egg by candling late in incubation. And yes, you should see it moving along the drawn down membrane.
for all 3 eggs!! You can do it!! Read this:
I actually just got done reading that! Wanted to have my ducks in a row before I did anything. One has the beak sticking through, the other does not but I almost certain there is a small slit in the membrane. my humdity is 75-80, because when I found a few clears at day 7 I stuck different ones in. So I am hand turning those three until these hatch (dreading bringing the humidity back down). And I am a peeker, looking through the plastic will never be good enough. And I was candling weird egg, the air cell has grown since day 18. I have to turn the younger eggs in a bit. I will get a picture then.
