Welcome to our nightmare! This happens to everyone at some point. It feels like a punch in the stomic to find eggs to cold or to hot. Just get the temp back and hope for the best. I've had EVERYTHING happen and in the end everything was ok. But make no mistake about it, you will loose sleep! Then when the little critter hatches out and someone try's to talk you down in price just say "NO", you try to do it"! Vic.......pic ....maybe this will make you feel better. I killed a clutch of these fooling around with the temps.to improve on the last years hatch rate! AHHHHHH!..NEVER GIVE UP.
