Well today is day 23 and this is our first hatch in the incubator. I am a little confused because most pictures that I have seen the chick pips the top of the egg. I have one egg and the pip is on top and another I see shell but can't see were it is pipping. Is it normal that a chick might pip on the bottom of the egg? Just really want to make sure this first hatch goes ok as the kids and I are very excited.
