Hello everyone. Tomorrow is hatch day but I have 2 external pips already. One pipped early this morning, around 1am and started zipping around 10am. It is now 7pm (9 hours later) and there has been no progress in the zip. If I shine a flashlight in at an angle, I can see movement in the egg around the zip but like I said, no progress in 9 hours. Humidity is averaging 65 to 75% right now, which is the same as my last hatch (it had 100% hatch rate). When should I assist, if at all?
