mine pushed one out, i took it in and but it in the bator then two days before hatch i took it and others do the same day and set them under her. then i found on, that had pipped and she smashed, out of the nest. i thought for sure it was dead, very cold and not moving. i put it back under her and all of them hatched.
my mom said to me "so much for watching temps and humidity and going crazy...."
