corn snake trouble

Question
I have a crimson corn snake and she is 1ft 6in and latley i started fedding bigger mice there white and about an inch and a half long and after the first one her skin shed is flaky and her skin has ripples in it do you know whats wrong thankyou

Answer
I doubt the skin problem has anything to do with the change in meal size.  Flaky shedding is usually a sign of low humidty.  Rippling is not something I think I've seen but I can't SEE what you're describing.  Can you post a pic of the skin so that I can see what you're talking about?
