It depends on your snakes Brian. I keep some together, both young corns and adults, and I generally don't have a problem. I keep a pretty close eye on the so that way, I can avoid a problem BEFORE its happens. Some of my females are cagemates during the off season just to help with space. Lately I've been staying at an apt until my house is built, so its kinda small. I keep my males sperate though, that way I don't have any problems with territorial combat. I haven't had a problem with cannibalism yet between hatchlings or adults. That doesn't mean I never will, but all hatchlings that are kept together have been together since hatching. If not, then they are kept in i think 32 oz deli cups with hides and water.
