Just an FYI, I am not your average PET owner even though I just own one boa and one Royal as a pet. I go through somewhat berserk amounts of research on animals I own. Including the dogs that I have been protection training for the last 13 years.
IF you are at all interested in boas and big constricting snakes there are several books and research pages available.
This particular web page caught my attention a while back and I bookmarked it.

You can see the massive amount of research and sighting involved here. Several experts are mentioned in this work.
Though it is not specific to our conversation here, there is mention of boas going "solo" in the wild. However there is also mention of some denning together in Dominica and some laying side by side during basking for increased thermo regulatory benefits.
I'm sorry this is WAY of topic and I really only wanted to tell Expensive Hobby I was excited and enjoyed the snakes. I loved the pics and only wish for good things.
My ONLY mention of the separate caging was based on research and good advice from credible keepers like Evenstar and a whole host of other captive owner breeders.
Outside of that, I'm a complete nobody.
Enjoy this link though. If you like constrictors, it's a good read.
FYI. You have to scroll a long way down to get to the parts that include the BC.
