Well, right now, they are probably seeking a position in the cage where they feel the most secure since your home is a new environment for them. Once they settle in and realize there's no boogy man waiting for them, they'll start to thermoregulate more.
As you've noted, your temps need to be adjusted a wee bit. I've found that my boas tend to like slightly cooler temps than my pythons. And the Argentines like it even cooler. I keep my BCIs at 77-78 ambient with an 88 hotspot. Humidity is good at about 60% +/-.
I've also found that belly heat seems to be better for babies, but radiant heat panels do fine for adults if that is what the keeper wants to do.
Hey Gio - thanks for posting that link! I think I'm gonna be on vacay for awhile reading that too..........![]()
