I have this egg that is sort of pipped.  Last night the chick pecked a chunk of shell off but I don't think it pierced the membrane.  That was a good 18 hours ago and there has been no progress made on that egg.  I can hear it chirping inside the egg... at least I think it's the one chirping.  Should I let nature take it's course or is this a situation where I might need to intervene?
 
edit: it looks like the membrane has been pierced, but it's a hole no bigger than the end of a toothpick. very small.
