Farmerpete here. My wife says she hears a peeping noise from our ready to hatch eggs. There are a couple of eggs on the wire screen that have the beak whole in the egg. my hearing is very bad and I told her that I don't see how they can make a peeping sound until they come out of the shell. I have 22 yellow buff eggs on the wire screen ready to hatch in the next day or so, and like I stated , so far there are 2 eggs in the process of hatching. Can they make a peeping sound pryor to comming out of the shell???
