I have lots of pipping and zipping going on in my bator - 2 are successfully out so far. YAY!! Didn't have great luck with this last time. However I have one chick who has pipped zipped and worked off the top of the egg so top half of it's body is out. He/she has been trying to get the rest of the way out for a couple hours now, but can't seem to do it. Should I worry? I have 4 more eggs that are pipping now and I'm seriously fighting the urge to open the bator to help the stuck one out.
