One of my muscovy eggs has pipped but not zipped after 24 hrs.  There is a break on the small side of egg.  I can see his beak in the air sack but can't tell if he's resting.  If he's moving it's only the tiniest bit.  What do I do?  4 have hatched successfully. Worried about this little guy!  Please help!
