I have three cochin banty eggs and four silkie eggs. Four have pipped, but I think I screwed one up. A cochin egg was oval shaped instead of having a small end. when I saw the pip, I candled it and found the pip at the wrong end. It was below the air cell. So I took tweezers and chipped away some of the shell from the pipped area and over to the air cell, but I didn't go through the membrane. That way, as the chick tries poking through the soft areas, it would work it's way over to the air cell. Well, it worked. I watched the chick poking at the membrane and it followed where I chipped out and poked through it. But now I'm afraid he'll dry out. I have the humidity at 68% right now. It's chirping and from the looks of it's beak, it's head is in the right position, but I can't tell about the rest of him at this point. I may have to put a wet paper towel arond it.
