Got a call just now about a dead broody and need help. Update

I got a call 20 minutes ago from a lady down the road, she got my number from a mutual friend. She had a broody hen in her yard on 15 eggs around 2 weeks (she didn't know for sure but said she was sure at least 2 weeks). A dog came in her yard and killed the hen and broke a few eggs. She wanted me to put the eggs in my incubator to see if they will still hatch. She had already disgarded the cracked egg that had a chick in it so I couldn't see it to try and tell how far along they are. My question is 2 are cracked but not leaking should I put them in or toss them, and if I have no Idea what day they are on what would be the best thing to do as far as turning and humidity? The hen wasn't her's but her neighbors who told her just to toss the eggs, she wants the babies back if they hatched and offered me money to try to save them ( I of coarse told her I didn't want money but would do what I could). The eggs were very cold when I got them but this just happend 2-3 hours ago would they still be ok.

UPDATE:
They started hatching yesterday morning but I had to go help a freind move all day and didn't get home til late. When I got home 10 had hatched, which included the 2 that had cracked shells. by this morning 3 more had hatched. I was gone so my husband not knowing call them to come get the 13 that had hatched so no pictures of them. He gave up on the last egg but I didn't and just a minute ago it hatched. I got pictures of him, Which is what 5 of the others looked like and 8 looked like maybe BR since the were black and white with spots on thier heads. I am so glad I listened and put that wax on the cracks. all 14 eggs hatched and I feel really great for being able to help out!

 

Ok I called her because the eggs look so clean and she said she wiped them off with damp paper towels. I hope this didn't hurt them but I candled 1 and it seemed to be moving still. The egg looked full, I will put wax on the cracked ones. they are both cracked near the large end so maybe it didn't hurt the membrane. Tomorrow I will try to candle them and see how many are even fertile or growing. I really don't like doing staggered hatchs so I might have to pull out the cooler bator for these. I have turkey eggs and chicken eggs in my bator already. Thanks for the help!

 

Well a bit of good news, I candled them all this morning and all 14 have movement in them even the 2 that are cracked. They look very full so shouldn't be long, I guess when I see wiggling eggs I will up the humidity. Crossing fingers they do ok. Thanks for the advise!!
