The Wait for Chicks

We tried to candle the dozen eggs that Lola is trying hatch a couple nights ago.  Having never done it before and not wanting to have the eggs away from her for very long, we didn't get a real good idea of how many eggs looked viable.  I could definitely see formations in some of them, but couldn't see anything in the green eggs. 

This morning when I went out to the brooding box to be sure she had food and water, I found one egg outside the nest and it was covered with goo - like she had deliberately removed it from the nest.  (Would a hen do that??)

I lifted Lola up to check on the others and she only had 10 eggs left.  It looks like one of them broke or exploded (which can sometimes happen when the egg isn't fertilized and it's being heated constantly from the hen sitting on it).  It also appears that she ate most of it after it opened up.  There was some pieces of shell leftover. 

The 10 remaining eggs are messy now with whatever came out of the broken egg and I don't know whether they'll be able to survive.  Not sure whether I should try to clean them up or just let nature take its course.  Research time!
