I'm asking this because I am just really curious. Not because I have multiple snakes housed together.
I see a lot of posts saying don't house 2 bps together because it can be really stressful.
However I see a lot of breeders with hatchlings and younger snakes being housed together as well as when I go to my exotic store.

Is there a reason why it is okay to house younger snakes together? But not adult snakes?
