Today is day 14.  Momma was off her clutch for a few minutes so I took time to check on the eggs.
Glad I did.  Found a broken egg in the nest box.  Got that cleaned up and dry wiped the eggs.  Took time to candle them.  There were 12 under her, so I am guessing she got rid of at least one (I did find one outside the nest box a day or two into the brood), one that was broke and another was a fake egg.
So, started with 15, 12 present today, including the broken egg.  Decided to candle the eggs.  Of the 11 left in the box, 8 are viable (although 1 seems not as developed as the other 7). Removed the blanks, cleaned up momma and let her sit again.
I also have another in the broody breaker box and one more that started acting broody today.  I removed all eggs, including the fake eggs from the boxes.
It has been a stressful brood for my broody momma.  I think the presence of other broodies has her stressed.  I should have gone with my first instinct to move her to an area of the coop that I can close off to the other hens.   Hindsight is great!
Another 5-7 days should yield 7-8 baby chicks.  
My broody in the broody breaker box is now in there 4 days.  I am hoping tonight, when I release her she stays broken.  I am going to have to have that box for the next girl.
