Today is day 20 and I have one egg pipped (this is my first hatch). However, it has pipped on the underside of the shell (it pipped in the right end, just not on the upper part of the shell). Is this normal and will it be okay? I hear it peeping from time to time and see movement. I know y'all probably get tired of answering stupid newbie questions, so sorry if this has been asked a zillion times before (I searched and couldn't find anything)...
