Hi all, this is my first time posting. I am hatching chicks for a homeschool project for my son. It's been a wonderful learning experience for our whole family. Yesterday we made it to day 19 and one of the chicks started to pip. It will be 24 hours by about noon today, and it still hasn't started to zip. Should we assist in any way or just leave it alone? It's definitely still alive as we can hear it peeping from time to time. We can also see movement inside, looks like it's opening its beak over and over or maybe it's breathing. I thought because it started pipping a couple days early it may be ok to leave it a bit longer. None of the other eggs have pipped yet. Any advice greatly appreciated! Thanks!
