Suz, I almost lost one that had pipped and made no progress. Watch that the membrane does not turn completely white, if so it has dried out. Go to the main index on incubating & hatching and there is a sticky at the top to tell you when and only when you should intervene. I had to do that to one chick (someone on this board named Indy and the name stuck)and it is very healthy now. I freaked out because when I would see a pip I waited for hours with nothing happening. It takes 12 hours or more before they are ready to zip. Takes about 15-30 min. to zip out. At least, that is how it happened for me the past two days. Keep us posted.
