Hi there I am new to hatching eggs and needed to ask a few questions. I have a standard black cochin hen setting on 9 eggs I got from a friend because all my hens are just starting to lay. Sunday will be her 21st day to sit. When I looked under her this moring one egg had a little hole in it. I assume this is a pip or peep. What is the difference? What is the amount of time from this to hatching? Also, she is in a pen with a speckled sussex rooster and 2 silver laced wyandotte hens. When would it be safe to move her to a brooder we have in the barn? Can I do it tonight or should I wait till the eggs have hatched? Thanks ,any advice would be appreciated.
