I place my eggs on a damp paper towel after they are cut, but I cut around day 57. You might want to put a small squirt bottle of water (distilled or saline would be even better) in your incubator until the temperature of the water is the same as your incubation temperature. Then you can gently hydrate the neonate. At day 59, they should be just about ready to come out.

On your next clutch, you might want to wait a little longer before you cut. Day 50 for a first time clutch is a little early.

Good luck. Hope everything is healthy out of the egg.
