5 of my eggs have hatched and been out of the bator since Friday afternoon, I have 2 more eggs that have pipped and been at it for over 36 hours, 1 of the eggs where the pip is has 2 toes sticking out of it but no beak and has for about 24 hours, it is making alot of noise and moving the toes alot but no more of the egg has pipped, is this normal?
