Zebra Finch Nest and Eggs Knocked Down?

We have a pair of zebra finches. They built a nest and laid 2 eggs which surprised us because we got them from someone that told us they where just a few months old. Never the less things where going great, the dad was brining twigs to make a roof and they where taking turns nesting on the eggs.

The eggs are probably about 5 days old when this happened. My wife has her 21 year old disabled daughter over on the weekend; she went to work this morning. I usually wake up at 9am and feed her daughter eggs before she takes her meds. Well I wake up to her daughter half in the bird cage. She must of wanted to see the eggs and she knocked down the nest and eggs. I'm so sad. I used a blueberry carton to put the broken nest into and rescued the 2 eggs.

At first they wouldn't go near it, but now she is sitting on them and he is making the new nest roof like before. I'm sure our daughter won't do this again as I made it very clear she may have killed the birds. But do these eggs have any chance of making it with being dropped and then God knows if she played with them or handled them? Please let me know how bad this is. The eggs seem fine, but idk.
