I have a pip!!! I'm a greenhorn at this. This is my first hatch ever. Here's my question... It hasn't changed in 6 hours. I can hear him/ her peeping away in there. Everytime it sees my flashlight it peeps. I soooooo want to flick a piece of that shell off. LOL How long is too long to wait?? Also, can they peep in there and be heard before they pip?
