Aww No way, but it would be a good idea, to talk with her that sometimes something's can happen and to be happy for the ones that do hatch, and if none don't its still ok and that maybe it was something with the eggs and you could try again.
At least for me I like my kids to know about it all and that its just the way of life sometimes.This way they expect the worst but hope for the best and don't get let down if it doesn't turn out the way we want it too.
Good luck and please let us know what happens!
How long have they been incubating? Have you candled? This would be a sure way of telling if they are still alive! If they are over a week old you can candle if a little longer you could for sure see movement when candling, my kids LOVE to see the babies moving inside, someone once told me, we are addicted to hatching these eggs and we don't know why, maybe its because its like a little womb, we can hold this little womb in our hands and see it when we candle! Much cheaper then a ultra sound!
Good Luck
