female pin suddenly changed?

[Skittles1101]

ive got a female pin & shes about 300-400 grams... Ive had her for 3 months and she was feeding like a charm every 5 days on f/t rat pups. I was feeding her in a separate enclosure every time w/o any problem...about 3-4 weeks ago she started acting stressed all the sudden (crawling around a lot & not staying under her hides) and it was taking some work to get her to take food...then she went through a shed a few days ago and now she wont take rats at all..whether its in her cage or not...only thing I changed at all was I re-positioned her hides about that time...didnt think that would be a big deal?? any suggestions to why she all of the sudden became fussy

She's probably hungry. A rat pup for a 300-400 gram snake is quite small, even on a 5 day feeding schedule. At the least I'd switch to weaned rats, maybe even switch to small rats once she takes a few weaned. A hungry ball python with roam.
