I was suggesting to leave it. Chicks starting to run around move the eggs all over the place. If I'm removing chicks then I right eggs, move back from edges of incubator and such but won't open it unless humidity is high and was opening the incubator anyway.
I had this exact thing just happen to me! But then the chick knocked back into the pipped egg and rolled him right side up again! I love how the hatched chicks peck on the unhatched eggs....it's like they are telling them "okay, time to come out now!"!
