Why would you leave a live prey item in the snake's enclosure for days? Overnight max... Anymore and you're just going to stress the snake out and likely kill the mouse/rat pup via dehydration/starvation.
The OPs set ups are not correct. Ball Pythons don't eat when their environments are not up to par, be it temperatures, humidity, hides, too much exposure, too much room activity, etc. Until the OP decides on his own that the snakes' enclosures are incorrect, the snakes will suffer until then.
