I have a broody Australorp sitting on some eggs. One of the eggs is chirping inside and I don't hear any chirping on the other eggs. When are they going to start pipping their way out of the shell? Today is the first time I heard chirping. What do I need to do next, if anything? I'm very excited, as this is my first time hatching out my own eggs. Is it bad to be moving the eggs and looking at them in my hand? Will the momma hen help the babies break free?
