Thank you for the advice mmk !
I am hoping the entire episode is the cool down and lack of feeding, but I am not ruling out worse possibilities. The collection included 3 adult and 2 sub adult BP's none of which show any signs of distress wobble etc.
The sad part is the snakes were in a Freedom Rack with built in heat (unplugged though) onsite rat breeding setup with pinkies, pups, fuzzies etc.
I am going to keep a close eye on them, try to warm everyone up and get some food in their bellies.
