I was about to throw out the last three eggs today bc I didn't see movement from the outside and the other ten had hatched Wednesday and thursday. I candled just to make sure and there was a chick moving and chirping. I can't see an air sac in it at all, so I don't have a clue how its breathing or of its going to run out of air. Should I poke a little hole in it or just let it be? It's a little egg so it may be just too big for the egg.
