Are these eggs alive?

[C Siena]

My broody hen sat on 11 eggs. She hatched out 7 chicks. She pushed the 4 unhatched out of the nest. I put the discarded eggs into my waiting incubator. The next evening there was 2 little guys fluffing up in the incubator. I gave them to the hen the next night when she was sleeping.
It was stated earlier, you've come this far with them, if they are not cracked and they don't skink keep going.

Yea! Way to go. Nothing to lose, all to gain...2 more chicks.
