I have two eggs that started external pip on Sunday. Today is early Tuesday morning. Yesterday and over the night they look like they are trying to zip as there are multiple external pips in a row. But none are breaking through the surface. I read once they zip you shouldn’t wait longer than seven hours, it has been longer then that since the second and third pips. Should I assist them, is this normal? I can hear chirping from one of them. Also they had their first external pip 41 hours ago. I’m so worried. I added pictures.
