How warm are they kept? I see you're in Florida, rats can easily die from heat stroke.

Check your water lines, make sure they are working. Keep rats cool, and feed them a good lab block.

If you still have some dying, look into getting more females from different sources.
How warm is too warm? Just looking for a ballpark figure. I had one die recently also. Very curious.
