Pet rat feet has red flaky skin

Question
My niece has two pet rats and one rat has red flaky skin on all of her feet. My niece doesn't know what to do. The feet aren't swollen

Answer
Check her ears -- are they red and flakey also?

If so, that might indicate an all-over skin condition. If not, could it be dandruff or excess porphin she's wiping onto her feet. Have you bathed her, and if so, did this alleviate the condition at all?
