17 of the 30 eggs hatched yesterday. Now we have 13 eggs in the incubator that I'm unsure about. I followed the advice in this post and listened to the eggs. I heard distinct chirping in one of them. What should I do? I can see where it pipped but it's not making any progress. Should I peel a bit of the shell back, or just let it be? I'm afraid to take it out because our house is fairly cold (60 degrees) and really don't have a clue what I'm doing.
