Only remove the shells after they have been emptied. Separate all newborns immediately because they can be cannibalistic even at this young age. Some newborns will eat immediately while others will wait until after their first shed. Most newborns will eat pinkies, while some will require scenting the pinkies with a lizard prior to consumption. The neonates should be fed twice a week and not hibernated the first year to accelerate their maturity.
Kingsnakes usually mature within two to three years.
