Corn snakes do not wrap snugly around your arm like pythons or kings. They tend to pick a direction and go for it. Though they are relatively small in body mass, they are quite strong. Always support the body and give free rein to the head. If the head starts going somewhere you don't want it to go, gently guide it into another direction.
Many snakes are nervous when introduced into a new situation with new people. Give them a couple of days to settle down before letting new people handle them.
In the wild, corn snakes tend to be secretive and are more active at night (nocturnal) or during the twilight hours (crepuscular). During the daytime, they may be found hiding under loose tree bark and beneath logs, rocks, and other debris. In colder regions, snakes hibernate during winter. However, in the more temperate climate along the coast they shelter in rock crevices and logs during cold weather and come out on warm days to soak up the heat of the sun. During cold weather, snakes are less active and therefore hunt less.
Corn Snakes are not naturally communal animals so cohabitation may not be ideal for your pet. There are also health concerns from premature breeding and egg binding to regurgitation issues and spreading of parasites like mites. Cannibalism is very uncommon but not unheard of, often caused by feeding snakes in the same enclosure. Never house more than 2 or 3 adults together. Snakes of opposite gender should not be housed together beyond 12-18 months to prevent pre-mature breeding.
Always provide additional hiding places for snakes who seek solitude.
