We were on Day 13 with our two Black Langshans x Splash Australorp (Roo) eggs when mites took over and she ate one of the eggs. The other egg looks to be dead as well but I have left it with her just in case. We have treated the mites with Sevin Dust as well as treated all the birds in that coop and cleaned it from top to bottom. All the nests, roosting spots, and dust areas were layered with Sevin Dust before being re-bedded. No mites were found today! 
She is determined to hatch out at least 1 baby so since we decided that we were just going to throw out the eggs from yesterday and today that we might as well give them to her to try and see what happens. The eggs are from Light Brahmas, Cuckoo Marans, and Black Langshans. All with a Splash Australorp Rooster.
Today is Day 0 for all but one of the eggs which is on Day 14, if this one magically isn't dead and hatches we will take it and raise it ourselves that way she can hatch out the others and not leave them behind. I will make sure that I re-candle the Day 14 egg on Day 18 to make sure it is still developing, if not then we will remove that egg for safety.
We will see what happens!
