First time hatching. Under a broody and incubator. Broody hatched all. Incubator is going amazing! 3 out, 2 pipped and 1 I have a question about. The 1 question, it pipped, a large hole, but didn't zip. It now has its whole beak out chirping and breathing. Should I still leave it? Will it go back in and zip? I certainly don't want to mess with anything and mess it up - but I also don't want to watch and let it go when I could be doing something.
