Had one or two pip yesterday. Today 6 more pipped. Now I have three unzipping. Another one however, sorta (I guess) unzipped the top, it fell off and the baby is still inside the membrane? There is a whole on the side where he pipped through but I can just see his beak. Should I just leave it alone? All of them are in an egg carton. Do silkies normally take this long too hatch? This is my first real silkie hatch. Thanks !
