thanks all.

There are some things which cause them to shed more often.

Does she have any injuries? She had some small wounds on her belly before the last shed and after that shed it looked a lot better.

What weight is she? she weighs +/-750 grams

Has she been introduced to any males? nope she is to young/small

so yeah maybe because of the small wounds on her belly. ah well i'll keep an eye on it
