i would make sure the humidity and temps are spot on and let her shed on her own. your preemptive intervention can stress her out even more if u try to force a shed. u could try the pillow case or this method or other methods only when it doesn’t go well. she might be off feed if she's in shed or if her husbandry is off.
it’s normal for BP’s to go off feed. they’re just fickle snakes and why some prefer Boa’s (for example) over BP’s b/c they are not picky and a garbage disposal for food. BTW how big is she for a yearling? she might be off feed or simply her body is readjusting after the growth spurt.
