rotten mice

So i feed my female lesser who is 5 months an adult mice. Everytime i check on her after she has eaten, she is in the cold hide for most of the day. Is there a chance that the mice will go bad in her stomach?
Now i started to take the cold hide out for a couple of hours after she has eaten so she stays in the warm hide.Then i place the cold one back later after so many hours. Is this okay or should i just leave both hides in after she has eaten.

Well, what are the temps.? Hot side and ambient? The hot side may be to hot, thats maybe why she is mostly in the cool side hide. But as long as your ambient temp. is good (80-83deg), you should be good. I would leave both hides in.

the warm side is around the 80s.

The hot side should be around 92 and the cool side around 80-83. With about 60% humidity.
