Good! Although you will find some people, including a big breeders, that do keep snakes together, there's never a problem until there's a problem. It's better to be safe than sorry. When you see snakes together, out in the wild, it isn't because they want to be together, it's because they are competing for the same optimal conditions. Keeping snakes separately, each can have free choice of where they want to be and what they want to do without having another snake taking over their area. No one is going to be fighting, getting gravid when they are too young, laying undetected eggs which subsequently die, spreading disease or eating anyone.
