have you ever tried the scotch tape over a hole in a egg that you were incubating? how did it turn out? I opened the lid to my incubator the other night to candle, I discovered a hole in the pointed end of a egg, the embryo was still viable at that time, They are not very far along in their development, 9 days today. The only thing I can think of is when I was putting the lid back on it is I punctured it with the arm for the rotator on the auto move, the hole is about the same size. So I put scotch tape over it. I just don't want to keep it in there if there is a risk of explosion and messing up the rest of the hatch, 5 out of 6 look viable.
